Abstract
Stereoselective synthesis of a new hexanor(C23-C28)castasterone-20,22- ethyl diether 22 has been achieved in sixteen steps from cheap and rea dily available 16-dehydropregnenolone acetate. This new brassinosteroi d has shown typical brassin activity in mung bean epicotyl bioassay. ( C) 1997 Published by Elsevier Science Ltd.
