Assignment of Configuration by Mitsonobu Reaction in the 13α-Methylgonane Series
摘要:
17-Ketosteroids in the 13alpha-methyl-gon-9(11)-ene series almost exclusively undergo nucleophilic attack from the alpha-face. Intramolecular capture of a cyclopropyl carbinyl cation, generated under Mitsunobu conditions unequivocally confirms the stereochemical course.
