28-Homobrassinolide has been synthesized from stigmasterol in an overall yield of 21%. The biological activity of 28-homobrassinolide, brassinolide, 24-epiibrassinoide, 22S,23S,24-epibrassinolide, and 22S,23S,28-homobrassinolides have been compared in the soybean epicotyl elongation assay. All the steroids except 22S,23S,28-homobrassinolide exhibited a similar biological activity, but the latter compound was substantially less active. There appears to be a correlation between biological activity and overall dimensions of the steroidal side chain.
