Abstract

NEW MATERIAL:A compound expressed by formula I (R<1> is H or OH-protecting group; R<2> is lower alkyl). EXAMPLE:A compound expressed by formula II. USE:Useful as a contraceptive agent capable of exhibiting inhibitory effects on follicle maturation. PREPARATION:A 6-hydroxy-17beta-estradiol derivative expressed by formula III (R<1> is protecting group) is reacted with a carboxylic acid derivative expressed by the formula R<2>COX or (R<2>CO)2O (X is OH or halogen), e.g. in a solvent, in the presence of an organic base at ambient temperature while being heated for 1-10hr.
