Claim:
A compound of the formula I wherein R 1 is unsubstituted or substituted cycloalkyl; R 2 is unsubstituted or substituted alkyl, unsubstituted or substituted alkenyl, unsubstituted or substituted alkynyl, unsubstituted or substituted aryl, unsubstituted or substituted heterocyclyl, unsubstituted or substituted cycloalkyl, or acyl; W is a moiety selected from those of the formulae IA, IB and IC, wherein the asterisk (*) denotes the position where the moiety W is bound to the 4-carbon in the piperidine ring in formula I, and wherein X 1 , X 2 , X 3 , X 4 and X 5 are independently selected from carbon and nitrogen, where X 4 in formula IB and X 1 in formula IC may have one of these meanings or further be selected from S and O, where carbon and nitrogen ring atoms can carry the required number of hydrogen or substituents R 3 or—if present within the limitations given below—R 4 to complete the number of bonds emerging from a ring carbon to four, from a ring nitrogen to three; with the proviso that in formula IA at least 2 of X 1 to X 5 are carbon and in formulae IB and IC at least one of X 1 to X 4 is carbon; y is 0, 1, 2 or 3; z is 0, 1, 2, 3 or 4 R3 which can only be bound to any one of X 1 , X 2 , X 3 and X 4 is hydrogen or unsubstituted or substituted C 1 -C 7 -alkyl, unsubstituted or substituted C 2 -C 7 -alkenyl, unsubstituted or substituted C 2 -C 7 -alkynyl, unsubstituted or substituted aryl, unsubstituted or substituted heterocyclyl, unsubstituted or substituted cycloalkyl, halo, hydroxy, etherified or esterified hydroxy, unsubstituted or substituted mercapto, unsubstituted or substituted sulfinyl, unsubstituted or substituted sulfonyl, amino, mono- or di-substituted amino, carboxy, esterified or amidated carboxy, unsubstituted or substituted sulfamoyl, nitro or cyano, with the proviso that if R3 is hydrogen y and z are 0; R4 is—if y or z is 2 or more, independently—selected from a group of substituents consisting of unsubstituted or substituted C 1 -C 7 -alkyl, unsubstituted or substituted C 2 -C 7 -alkenyl, unsubstituted or substituted C 2 -C 7 -alkynyl, halo, hydroxy, etherified or esterified hydroxy, unsubstituted or substituted mercapto, unsubstituted or substituted sulfonyl, unsubstituted or substituted sulfonyl, amino, mono- or di-substituted amino, carboxy, esterified or amidated carboxy, unsubstituted or substituted sulfarnoyl, nitro and cyano; T is methylene (—CH 2 —) or carbonyl (—C(═O)—); and R11 is hydrogen, hydroxy, halo, C 1 -C 7 -alkyl, halo-C 1 -C 7 -alkyl, cycloalkyl, halo-substituted cycloalkyl, C 1 -C 7 -alkoxy, halo-C 1 -C 7 -alkoxy or cyano, or a salt thereof.
