Abstract

Naphtho-imidazoles and -oxazoles of formula (I) and their acid-addn. salts are new. In (I) R and R1 are H, halogen, 1-6C alkyl, or alkoxy; R2 is H or halogen; A is -N:CR3-NR4-, -NR4-CR3:N- or -O-CRY:N-; R3 is 1-6C alkyl, 5-6C cycloalkyl or (CH2)n-NR5R6; n is 1-3; R5 is H or 1-6C alkyl; R6 is 1-6C alkyl; or NR5R6 is a 4- to 7-membered satd. heterocyclic gp. opt. also contg. O or a further N and opt. substd. by 1-6C alkyl, 2-6C alkenyl, 5-6C cycloalkyl, 2-6C aliphatic acyl, Ph opt. substd., benzyl, halobenzyl or pyridinyl; R4 is H, 1-6C alkyl, 5-6C cycloalkyl or (CH2)n-NR5R6; and R7 is (CH2)n-NR5R6. Provided that (a) when A is other than oxyazole residue, then one of R3 and R4 is (CH2)n-NR5R6; and (b) when R3 is (CH2)n-NR5R6, then NR5R6 is not morpholino or piperidino.
