                                摘要:
                                5-Methyl- and 5-ethyl-furylalkylcarboxylic esters of norethisterone (17 alpha-ethynyl-17 beta-hydroxyestr-4-en-3-one) were prepared in high yield in the presence of thallous ethoxide. The activities of these compounds as long-acting contraceptive agents have been evaluated.
