New heterocyclic compounds represented by the following formula: ##STR1## wherein: R and R.sub.1 are independently selected from hydrogen, hydroxy, (C.sub.1-4)alkyl, (C.sub.1-4)alkoxy, (C.sub.3-5)alkenyloxy, (C.sub.3-5)alkynyloxy, (C.sub.3-6)cycloalkyloxy, or halo or taken together represent a methylenedioxy group; the symbols W and A are defined as follows: 1. W is the nitrogen atom and A is the group ##STR2## in which the carbon atom bearing the radical R.sub.2 is linked to the benzene ring and R.sub.2 is hydrogen, hydroxy, (C.sub.1-4)alkoxy or (C.sub.2-4)aliphatic acyloxy; 2. W is the group =CH-- and A is --CH.sub.2 --, --CH.sub.2 --CH.sub.2 -- or --CH=CH--. The compounds have antireproductive utility.
