Pregnane analogues of brassinolide and castasterone have been prepared which have an ester function with five carbon atoms at the 20 position. When tested by the bean second internode bioassay, the most efficient substance is
Analogues of brassinolide and castasterone, containing an ester functionality with four carbon atoms in the position 20 of the pregnane skeleton, have been prepared. In the bean second internode assay the most effective compounds were (20
