SYNTHESIS OF NATURALLY OCCURRING BRASSINOSTEROIDS EMPLOYING CLEAVAGE OF 23,24-EPOXIDES AS KEY REACTIONS. SYNTHESIS OF BRASSINOLIDE, CASTASTERONE, DOLICHOLIDE, DOLICHOSTERONE, HOMODOLICHOLIDE, HOMODOLICHOSTERONE, 6-DEOXOCASTASTERONE AND 6-DEOXODOLICHOSTERONE

Eight new plant growth-promoting steroids (brassinolide, castasterone, dolicholide, dolichosterone, homodolicholide, homodolichosterone, 6-deoxocastasterone and 6-deoxodolichosterone) were synthesized by the regio- and stereoselective ring-opening reactions of 23,24-epoxides prepared from stigmasterol.

Stereoselective syntheses of dolicholide (3), (22R,23R)-2α,3α,22,23-tetrahydroxy-B-homo-7-oxa-5α-ergost-24(28)-en-6-one, and dolichosterone (4), (22R,23R)-2α,3α,22,23-tetrahydroxy-5α-ergost-24(28)-en-6-one, were achieved from the known (22E,24S)-2α,3α-diacetoxy-5α-stigmast-22-en-6-one (5) which is readily available from stigmasterol.The key step in the construction of the (22R,23R)-vicinal diol function in the steroidal side-chain was new and used the method of chelation control.
