Two naturally occurring C 29 ‐brassinosteroids, 25‐methyldolichosterone ( 1 ) and 25‐methyl‐2,3‐diepidolichosterone ( 2 ), were synthesized from stigmasterol. 25‐Methylcastasterone ( 3 ) and 25‐methylbrassinolide ( 4 ) were also synthesized, and the latter was found to be a more potent plant growth‐regulator than brassinolide itself.
