New compounds of the formula
wherein:
Ar1 and Ar2 are each independently optionally substituted phenyl;
R', R2 and R3 are each independently hydrogen or alkyl;
a is an integer from 1-3;
b is an integer from 1-3;
c is an integer from 0-2; and
d is an integer from 0-2, such that (c + d) equals 0-2; and the pharmaceutically acceptable non-toxic acid addition salts thereof, are spermicidal and, therefore, are useful as contraceptives.
式中的新化合物
其中
Ar1 和 Ar2 各自独立地为任选取代的苯基;
R'、R2 和 R3 各自独立地为氢或烷基
a 是 1-3 的整数
b 是 1-3 的整数
c 是 0-2 的整数;以及
d 是 0-2 的整数,这样 (c + d) 等于 0-2;其药学上可接受的无毒酸加成盐具有杀精子作用,因此可用作避孕药。
