该中间体在本合成路线中的序号:(XLV)Elimination of thiophenol from (XLIII) by means of CaCO3 in refluxing toluene gives the unsaturated lactone (XLIV) with the (E)-vinylene bond. The alpha,beta-epoxidation of the unsaturated lactone (XLIV) with H2O2 and NaOH in methanol/dichloromethane affords the monoepoxy lactone (XLV) regioselectively, which is finally submitted to a regioselective ring opening with diphenyl diselenide and NaBH4 in THF.
