合成路线1
该中间体在本合成路线中的序号：(LI)The reaction of (R)-glycidol (XLVI) with dihydropyran (DHP) and PPTS in dichloromethane gives the protected glycidol (XLVII), which is treated with the lithium acetylide (XLVIII) and BF3/Et2O in THF to yield the acetylenic alcohol (IL). The protection of the OH group of (IL) with Mem-Cl and DIEA in hot dichloroethane affords compound (L), which is treated with PPTS in methanol to provide the primary alcohol (LI). The oxidation of (LI) with oxalyl chloride in DMSO/dichloromethane gives the corresponding aldehyde (LII), which is treated with Me-MgBr in ethyl ether to yield the secondary alcohol (LIII). The oxidation of (LIII) with TPAP and NMO in dichloromethane affords the methyl ketone (LIV), which is condensed with the phosphine oxide (LV) by means of BuLi in THF, providing the adduct (LVI). The reaction of (LVI) with N-iodosuccinimide (NIS) and Cy2BH in ethyl ether gives the iodovinyl compound (LVII), which is treated with acetic anhydride, yielding the intermediate (IX).
