主　　题：In ITS CYCLOPENTYL ETHER SYNTHESES OF AMINO ESTERS OF ETHYNYL ESTRADIOL AND ITS 3 

摘      要：In an attempt to search for the influence of structural variation of ethynylestradiol on its physiological properties,syntheses of 3—,17β—monoestersand 3,17β—diester of the steroidal diol or its 3—cyclopentyl ether have *** acylation of the 3—hydroxyl group of ethynyl estradiol by appro-priate phthaloyl imino acyl chloride can be effected smoothly and simply atroom temperaturet pyridine being employed as reaction ***,
