摘要

The present invention relates to tetrahydroquinoline derivatives having general formula (I) or a pharmaceutically acceptable salt thereof, wherein R1 is formyl, (1-6C)alkylcarbonyl or (1-6C)alkylsulfonyl; R?2 and R3¿ are H or (1-4C)alkyl; R4 is phenyl; R5 is (1-4C)alkyl; Y-X is (CO)-O, (SO)¿2?-O, NHC(O)-O, NHC(S)-O, OC(O)-O, bond-O, C(O)-NH, S(O)2-NH, NHC(O)-NH, NHC(S)-NH, OC(O)-NH, bond-NH, NH-C(O), O-C(O), NH-S(O)2, or O-S(O)2 or Y-X is a bond; R?6¿ is H, trifluormethyl, (1-6C)alkyl, 1- or 2-adamantyl(1-4C)alkyl, (2-6C)alkenyl, (3-9C)heteroaryl, (3-6C)cycloalkyl, (2-6C)heterocycloalkyl, (1-4C)alkylthio(1-4C)alkyl, (6-10C)aryl(1-4C)alkyl, (3-9C)heteroaryl(1-4C)alkyl, (3-6C)cycloalkyl(1-4C)alkyl, (2-6C)heterocycloalkyl(1-4C)alkyl, R8, R9-aminocarbonyl(1-4C)alkyl, R8, R9-amino(1-4C)alkyl, R8-oxycarbonyl(1-4C)alkyl, R8-oxy(1-4C)alkyl, R8-carbonyl(1-4C)alkyl or (6-10C)aryl; R7 is H, (1-4C)alkyl, (1-4C)alkoxy, halogen, trifluoromethyl, cyano, nitro hydroxyl; and R8 and/or R9 is H, (1-4C)alkyl, (2-4C)alkenyl, (2-4C)alkynyl, (6-10C)aryl, (3-9C)heteroaryl, (6-10C)aryl(1-4C)alkyl, (3-9C)heteroaryl(1-4C)alkyl, (3-6C)cycloalkyl(1-4C)alkyl, (2-6C)heterocycloalkyl(1-4C)alkyl, (1-4C)(di)alkylamino(1-4C)alkyl, (1-4C)alkoxy(1-4C)alkyl, (1-4C)alkylthio(1-4C)alkyl, (1-4C)alkylcarbonylamino(1-4C)alkyl, (1-4C)alkoxycarbonyl(1-4C)alkyl, (1-4C)alkoxycarbonylamino(1-4C)alkyl, (3-6C)cycloalkyl, (2-6C)heterocycloylkyl, or R?8 and R9¿ may be joined in a (2-6C)heterocycloalkyl ring. The present invention also relates to pharmaceutical compositions comprising said derivatives and the use of these derivatives to control fertility.
