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.
以下是由以下公式表示的新杂环化合物:
##STR1##
其中:R和R.sub.1独立选择氢,羟基,(C.sub.1-4)烷基,(C.sub.1-4)烷氧基,(C.sub.3-5)烯基氧基,(C.sub.3-5)炔基氧基,(C.sub.3-6)环烷基氧基或卤素,或一起表示为亚甲二氧基基团;符号W和A定义如下:
1. W是氮原子,A是群##STR2##
其中,携带基团R.sub.2的碳原子与苯环相连,R.sub.2是氢,羟基,(C.sub.1-4)烷氧基或(C.sub.2-4)脂肪酰氧基;
2. W是基团=CH-,A是--CH.sub.2--,--CH.sub.2--CH.sub.2--或--CH=CH--。
这些化合物具有抗生殖作用。
