摘要:
The present invention is related to a novel intermediates and processes which are useful in the preparation of certain antihistaminic piperidine derivatives of the formula wherein W represents —C(═O)— or —CH(OH)—; R1 represents hydrogen or hydroxy; R2 represents hydrogen; R1 and R2 taken together form a second bond between the carbon atoms bearing R1 and R2; n is an integer of from 1 to 5; m is an integer 0 or 1; R3 is —COOH or —COOalkyl wherein the alkyl moiety has from 1 to 6 carbon atoms and is straight or branched; each of A is hydrogen or hydroxy; and pharmaceutically acceptable salts and individual optical isomers thereof, with the proviso that where R1 and R2 are taken together to form a second bond between the carbon atoms bearing R1 and R2 or where R1 represented hydroxy, m is an integer 0.

The present invention is directed to compounds represented by Structural Formula I and pharmaceutically acceptable salts, solvates and hydrates thereof, and methods of making, methods of using and pharmaceutical compositions having compounds represented by Structural Formula I and pharmaceutically acceptable salts, solvates and hydrates thereof: In Structural Formula I, n is 2, 3, or 4; V is O or S; W is O, S, or SO2; R1 is H, a C1-C4 alkyl, phenyl or trifluoromethyl; R2 are each, independently, H, a C1-C6 alkyl, an aryl-C1-C6 alkyl, a cycloalkyl-C1-C4 alkyl, an aryl, a cycloalkyl, or together with the phenyl to which they are bound form naphthyl or 1,2,3,4-tetrahydronaphthyl; R3 are each, independently, H, a C1-C6 alkyl, an aryl-C1-C6 alkyl, a cycloalkyl-C1-C4 alkyl, an aryl, or a cycloalkyl; R4 are each, independently, H, a C1-C4 alkyl, an aryl, or benzyl; R5 are each, independently, H, a substituted or unsubstituted aryl or a heteroaryl, provided that at least one R5 is a substituted or unsubstituted aryl or a substituted or unsubstituted heteroaryl; and R6 is H, a C1-C4 alkyl, or an aminoalkyl.

The present invention relates to a novel process for preparing cis-4-O-protected-substituted-2-cyclopentenol derivatives comprising, a) dissolving a 4-O-protected-2-cyclopentenone in a suitable organic solvent; and b) treating the solution with a suitable Lewis acid and a suitable reducing agent at a temperature of from about -100.degree. C. to about 20.degree. C. The cis-4-O-protected-substituted-2-cyclopentenol derivatives are useful intermediates in the preparation of various cyclopentanyl and cyclopentenyl purine analogs which are useful as immunosuppressants and in the preparation of various prostaglandins.
