Tricyclic amides of formula (I), their enantiomers, diastereoisomers, and salts are new. R<1> = 1-4C alkylene, opt. substd. by alkyl, OH, alkoxycarbonyl, or COOH; R<2> = H or alkyl; R<3> = a group R<31> which is -C(=X')-(CH2)n-R<5> or a group R<32> which is -C(=X)-NH-(CH2)m -R<6>; m and n = 0-3; R5, R6 = H, alkyl, alkenyl, alkynyl, cycloalkyl, or di-cycloalkyl-alkyl (all opt. substd.); X, X' = O or S; A = -O-A<1>-; A<1> = 2-5C alkylene, alkenylene, or alkynylene which may be substd. by alkyl, alkoxy, OH and oxo gps.; Y forms, with the benzene ring to which it is attached, a group Y<1> which is naphthalene, benzofuran, or benzothiophene, all of which may be partially hydrogenated, or indole; provided that the substitutions on alkyl, alkenyl, and alkynyl groups are halogen, alkyl, or alkoxy, while the substitution on cycloalkyl and di-cycloalkyl-alkyl groups are alkyl, alkoxy, hydroxy, or oxo. Alkyl, alkoxy, alkenyl and alkynyl groups have up to 6C, and cycloalkyl groups have up to 8C, and may be satd. or unsatd. Intermediates of formula (II) and (VI) are new. Z<1> = a reactive gp.; A<6> = 2-5C alkenyl opt. substd. by 1-6C alkyl. |
