摘要

Novel tricyclic compounds represented by the following general formula I I wherein: the symbol A represents one of the following groups -CH=CH- and -CH2-CH2-; R is selected from hydrogen, an alkyl group containing 1 to 5 carbon atoms, an alkoxy group containing 1 to 5 carbon atoms, hydroxy, or benzyloxy; R1 is selected from hydrogen or a lower alkyl group containing 1 to 5 carbon atoms; R2 is selected from hydrogen, methyl, carboxy, carboalkoxy in which the alkyl group contains 1 to 5 carbon atoms; di (alkyl)-carbamyl in which the alkyl group contains 1 to 5 carbon atoms, and hydroxy methyl. The compounds of the invention have anti-reproductive activity.
