CYCLOCARBAMATE AND CYCLIC AMIDE DERIVATIVES

摘要

This invention provides compounds of formula (I) wherein A and B are independent substituents selected from S, CH or N; provided that when A is S , B is CH or N; and when B is S, A is CH or N; and A and B cannot both be CH; and when A and B both equal N, one N may be optionally substituted with a C1 to C6 alkyl group; R1 and R2 are independent substituents selected from the group of H, C1 to C6 alkyl, substituted C1 to C6 alkyl, C2 to C6 alkyl, C2 t o C6 alkenyl, substituted C2 to C6 alkenyl, C2 to C6 alkynyl, substituted C2 t o C6 alkynyl, C3 to C8 cycloalkyl, substituted C3 to C8 cycloalkyl, aryl, substituted aryl, heterocyclic, substituted heterocyclic, CORA, or NRBCORA; or R1 and R2 are fused to form optionally substituted 3 to 8 membered spirocycl ic alkyl, alkenyl or heterocyclic ring, the heterocyclic ring containing one to three heteroatoms selected from the group of O, S and N; or pharmaceutically useful salts thereof. The compounds of this invention are useful as agonists and antagonists of the progesterone receptor and in methods of inducing contraception and in the treatment or prevention of benign or malignant neoplastic diseases.
