Dihydro or tetrahydronaphthalene derivatives (I) are new. Dihydro or tetrahydronaphthalene derivatives of formula (I), their stereoisomers and salts are new. R1 = H, 1-6C alkyl or 1-6C acyl (both optionally substituted); R2, R3 = H or 1-6C alkyl (optionally substituted); R2 + R3 = 3-7C cycloalkyl; R4 = aryl or heteroaryl (both optionally substituted); X = O or CH2; Y = OH, 1-6C alkyloxy or NR5R6; R5, R6 = H or 1-6 C alkyl (optionally substituted); R5 + R6 = 3- to 15-membered heterocylic (optionally substituted) or polycyclic ring, optionally comprising an additional O, S or N; and Z = single or double bond. Independent claims are also included for: (1) the preparation of (I); and (2) the intermediates compounds of formulas (V), (VI) and (VII). |
