Abstract

Brassinolide (1)) isolated from rape pollen (Brassica nupus L.) is known to exhibit plant growth regulating activity. Because of its interesting physiological activity and its novel structural features, much effort has been devoted in recent years to develop the synthetic route to brassinolide and its analogues.'Recently we succeeded in the stereoselective syntheses of brassinolide,'its enantiomer (22S, 23S, 24R)-22, 23, 24-epibrassinolide,'and ...
