The reduction of Delta(7)-6-keto-ergostane derivatives with Na2S2O4 in the presence of a phase transfer catalyst is performed and the effect of experimental conditions is discussed. This represents a safer and economic way for the synthesis of brassinosteroid analogs. (C) 1999 Elsevier Science Ltd. All rights reserved.
