The mechanism of hydrogenolysis was discussed. This facile and stereoselective introduction of 16β-ethyl and 17β-hydroxy groups was applied to the synthesis of 16β-ethyl-19-nortestosterone (TSAA-291,XIX), which shows strong antiandrogenic activity., 金沢大学大学院医学系研究科}, pages = {3203--3207}, title = {Studies on Antiandrogenic Agents.
