PROCEDURE

实验过程

A solution of 17β-cyclopropyloxy-androst-5-en-3β-ol (19.36 g, 58.9 mM) in acetone (1.9 L) is cooled to -3° C and then treated with Jones reagent (20 ml). The excess reagent is decomposed with methanol. The solids are removed by filtration. The filtrate is concentrated to a green oil which is purified by flash chromatography on silica gel to give 17β-cyclopropyloxy-androst-4-en-3-one (11.0 g, 57%).
