Stereoselective synthesis of a new hexanor(C23-C28) castasterone-20,22-ethyl diether from 16-dehydropregnenolone acetate and its plant growth promoting activity

Stereoselective synthesis of a new hexanor(C23-C28)castasterone-20,22-ethyl diether 22 has been achieved in sixteen steps from cheap and readily available 16-dehydropregnenolone acetate. This new brassinosteroid has shown typical brassin activity in mung bean epicotyl bioassay.
