3-Ethoxyandrosta-3,5-diene-17-one

The orally active progestational agent 17a-ethynyltestosterone (56) was subsequently obtained by Oppenauer Oxidation. Similarly ethynyla-tion of 3-ethoxyandrosta-3,5-dien-17-one followed by acid hydrolysis afforded the 17a-ethynyl compound (56). ... [Pg.65]

Sequential reaction of the spiro-epoxide (139), derived from 3-ethoxyandrosta-3,5-dien-17-one and Me3S+F, first with chloranil to establish the A4,6-3-oxo-function and then with diethyl malonate, allowed the isolation of the spiro-steroid (140 R = C02Me). Saponification and decarboxylation led to the derivatives (140 R = C02H) and (140 R = H) respectively.54 It has been demonstrated that the... [Pg.293]
