Abstract

A method for the preparation of racemic or optically active 13beta-ethyl-17alpha-ethynyl-gon-4-ene-on-17beta-ol, in which 13beta-ethyl-3-methoxy-gon-2,5 (10) racemic or optically active 17beta-ol diene is reacted with hydroxylamine, the 17-hydroxy group of racemic or optically active 13beta-ethyl-3 (hydroxyimino) -gon-4-ene-17beta-ol is oxidized to an oxo group obtained, the obtained racemic or optically active 13beta-ethyl-3- (hydroxyimino) -gon-4-ene-17-one is ethynylated, and 13beta-ethyl-17alpha-ethynyl-3- (hydroxyimino) - is hydrolyzed. Racemic or optically active gon-4-ene-17beta-ol thus formed. (Machine-translation by Google Translate, not legally binding)
