The possibilities of synthesizing various α-trifluoromethylated oxygenated heterocycles, starting from trifluoroacetaldehyde Me hemiacetal, through classic cyclization reactions, have been demonstrated. In this way, sixmembered cyclic compds., δ-lactones and also macrolactone derivs., bearing a CF3 group in a position α to the oxygen could be easily obtained through a RCM reaction. Bicyclic compds. could be also synthesized by an intramol. PausonKhand reaction.

Dehydrofluorination of 1-aryl-1,2,2,2-tetrafluoroethanes (ArCHFCF3) and 1-aryl-1-chloro-2,2,2-trifluoroethane (ArCHClCF3) using lithium hexamethyldisilazide (LHMDS) in THF at room temp. produced 1,2,2-trifluorostyrene and 1- chloro-2,2-difluorostyrene, resp., in very good isolated yields.

The present invention encompasses five-membered heterocycle-substituted benzenepropanoic acids (shown as I; variables defined below; e.g. 3-[4-[5-(3-cyano-4-isopropyloxyphenyl)-1,2,4-oxadiazol-3-yl]-3-methylphenyl]propanoic acid (II)) as well as the pharmaceutically acceptable salts thereof. The compds. are selective S1P1/EDG1 receptor agonists and thus have immunosuppressive, antiinflammatory and hemostatic activities by modulating leukocyte trafficking, sequestering lymphocytes in secondary lymphoid tissues, and enhancing vascular integrity. The invention is also directed to pharmaceutical compns. contg. such compds. and methods of treatment or prevention. The example I have utility as immunoregulatory agents as demonstrated by their activity as potent and selective agonists of the S1P/Edg1 receptor over the S1P3/Edg3 receptor; in particular, the example I possess a selectivity for the S1P1/Edg1 receptor over the S1P3/Edg3 receptor of >100 fold as measured by the ratio of EC50 for the S1P1/Edg1 receptor to the EC50 for the S1P3/Edg3 receptor as evaluated in the 35S-GTPγS binding assay and possess an EC50 for binding to the S1P1/Edg1 receptor of <50 nM as evaluated by the 35S-GTPγS binding assay. Although the methods of prepn. are not claimed, >100 example prepns. are included. For example, II was prepd. in 2 steps by first cyclizing N-hydroxy-3-methyl-4-[2- (tert-butoxycarbonyl)ethyl]benzamidine with 3-cyano-4-isopropyloxybenzoic acid using N-(3-dimethylaminopropyl)-N'- ethylcarbodiimide in MeCN and then hydrolyzing the result. For I: R1, R2, R3 and R4 = H, F, Cl, Br, I, CN, OH, C1-6alkyl, C2-6alkenyl, C2-6alkynyl and C1-5alkoxy, wherein said C1-6alkyl, C2-6alkenyl, C2-6alkynyl and C1-5alkoxy are each (un)substituted with 1-3 F, Cl, Br, I, OH, C1-8alkoxy and -O2H, and any two of R1-R4 may be joined together with the atoms to which they are attached to form a satd. monocyclic ring of 3-8 atoms optionally contg. 1 or 2 O atoms. R5 = F, Cl, Br, I, CN, OH, or (un)substituted C1-4alkyl, C2-4alkenyl, C2-4alkynyl and C1-4alkoxy; R6 = (un)substituted Ph, pyridinyl, pyrimidinyl, pyrazinyl, pyridazinyl and thienyl, and R6 may be substituted on two adjacent atoms to form a fused partially arom. (un)substituted bicyclic ring of 9-12 atoms optionally contg. one or two O or S groups, or both. U, V and W = - C(R9)- or -N-; X, Y and Z = -C(R11):, -O-, -N:, -N(R12)- and -S- such that the resulting ring together with Q and T form an arom. heterocycle; Q and T = >C: or >N-, with the proviso that both Q and T are not >N-; addnl. details are given in the claims.

215. Novel α-fluorinated cyclic phosphite and phosphinite ligands and their Rh-complexes as suitable catalysts in hydroformylation

By Odinets, Irina; Kegl, Tamas; Sharova, Elena; Artyushin, Oleg; Goryunov, Evgenii; Molchanova, Galina; Lyssenko, Konstantin; Mastryukova, Tatyana; Roeschenthaler, Gerd-Volker; Keglevich, Gyoergy; et al

Asym. cyclic phosphite and phosphinite ligands of a novel type bearing either a trifluoromethyl or pentafluorophenyl group were synthesized using >PCl or >PN< species and racemic fluorinated alcs. For example, 2,2,2-trifluoro-1-phenyl- 1-ethanol reacted with 2-chloro-1,3,2-benzodioxaphosphole giving 2-(2,2,2-trifluoro-1-phenylethoxy)-1,3,2- benzodioxaphospholene in 100% yield. The P-ligands were converted to complexes of RhIII(L)(Cp*)Cl2 type (where L = phosphite or phosphinite) and, in two instances, their stereostructures were evaluated by x-ray anal. These complexes along with in situ systems, formed from Rh(CO)2(acac) precursor and the corresponding ligand, were tested in the hydroformylation of styrene. Both systems provided excellent hydroformylation activities at 100 °C. Using the RhI in situ systems, moderate and high regioselectivities towards the branched aldehyde (2-phenylpropanal) were obtained at 100 and 40 °C, resp.

217. Silicon-induced diastereoselectivity of the catalyzed phosphorylation of 1-(perfluoroalkyl)-ω-(trialkylsilyl)alkan-1-ols

By Molchanova, G. N.; Shcherbina, T. M.; Petrovskii, P. V.; Kudryavtsev, I. Yu.; Zakharov, L. S. From Russian Chemical Bulletin (2004), 53(9), 2013-2019. Language: English, Database: CAPLUS, DOI:10.1007/s11172-005-0064-3

The stereochem. of catalytic phosphorylation of 1-(perfluoroalkyl)-ω-(trialkylsilyl)alkan-1-ols with pentavalent phosphorus acid monochlorides (phosphonochloridates, methyl(phenyl)phosphinic chloride, and phosphorochloridates) was studied. The effects of the structures of alcs. and phosphorylating agents on the degree of the reaction diastereoselectivity were investigated. Methylphosphono chloridates were found to react most stereoselectively; the diastereoselectivity of the phosphorylation is independent of the donor or acceptor character of substituents at the phosphorus atom, being detd. by their vols. In the series of silylalkanols, the diastereoselectivity of the reaction the higher the closer the Si atom to the reactive site of the mol., the larger the vol. of the perfluoroalkyl substituent, and the more pronounced the electronwithdrawing properties of the substituents at the Si atom. A reaction mechanism is proposed that rationalizes the stereoselectivity of the reaction.

For instance, reacting 2-isopropoxy-5- methylsulfonylbenzoic acid (prepn. given) with 1-(2-fluoro-4-trifluoromethylphenyl)piperazine gave piperazine II. I

showed an IC50 (μM) at GlyT-1 in the range of 0.006-5.0. Preferred I displayed an IC50 (μM) at GlyT-1 in the range of 0.006-0.05. Thus, I are useful in the treatment of illnesses based on the glycine uptake inhibitor, such as psychoses,

pain, neurodegenerative disfunction in memory and learning, schizophrenia, dementia and other diseases in which cognitive processes are impaired, such as attention deficit disorders or Alzheimer's disease.

221. The role of organic fluorine in directing alkylation reactions via lithium chelation

By Tenza, Kenny; Northen, Julian S.; O'Hagan, David; Slawin, Alexandra M. Z.

From Journal of Fluorine Chemistry (2004), 125(11), 1779-1790. Language: English, Database: CAPLUS, DOI:10.1016/j.jfluchem.2004.09.015

The fluorine of a fluoromethyl group displays a measurable chelation effect to lithium during α-methylation of an ester with lithium diisopropylamide (LDA) and Me iodide. A series of esters is compared with F, H and O, and the resultant diastereoselectivity is consistent with the intermediate capacity of F to chelate lithium relative to H and O. In a second system which involved comparing a tertiary org. fluorine with hydrogen, no such effect is apparent, most probably due to adverse steric effects. The abs. and relative stereochem. of the predominant diastereoisomers are confirmed by X-ray crystallog. of suitable cryst. derivs. in each case. It is concluded that there is a potential role for org.-bound fluorine to become involved in lithium chelation in well-designed enolate alkylation systems.

222. Remarkable Substituent Effects on the Oxidizing Ability of Triarylbismuth Dichlorides in Alcohol Oxidation

By Matano, Yoshihiro; Hisanaga, Teppei; Yamada, Hisatsugu; Kusakabe, Shingo; Nomura, Hazumi; Imahori, Hiroshi From Journal of Organic Chemistry (2004), 69(25), 8676-8680. Language: English, Database: CAPLUS, DOI:10.1021/jo0485740

Substituent effects on the oxidizing ability of triarylbismuth dichlorides were examd. by intermol. and intramol. competition expts. on geraniol oxidn. in the presence of DBU. The oxidizing ability of the dichlorides increases with increasing electron-withdrawing ability of the para substituents, and by introduction of a Me group at the ortho position of the aryl ligands attached to the Bi. The intermol. and intramol. H/D kinetic isotope effects obsd. for the competitive oxidn. of p- bromobenzyl alcs. indicate that the rate-detg. step involves C-H bond cleavage. Several primary and secondary alcs. were oxidized efficiently under mild conditions by the combined use of newly developed organobismuth(V) oxidants and DBU.
