Continuing a programme directed toward the synthesis of biologically active analogues and potential biogeneric precursors of brassinosteroids the new members 24-epiteasterone (2) and 24- epityphasterol (7) as well as their corresponding lactones 2-deoxy-3,24-diepibrassinolide (3) and 2- deoxy-24-epibrassinolide (8) have been synthesized starting fromergosterol.
