合成路线1
该中间体在本合成路线中的序号:(XIII)A Wittig condensation of [4-(methanesulfonylaminocarbonyl)butyl]triphenylphosphonium bromide (X) [the phosphonium bromide (X) is prepared bv reaction of 5-bromovaleryl chloride (Xl) with methanesulfonamide (XII) at 100 C to give N-methanesulfonyl-5-bromovaleramide (XIII), which is then condensed with triphenylphosphine in refluxing acetonitrile] with hemiacetal (IX) by means of Na in DMSO affords N-methanesulfonyl-9alpha-hydroxy-11alpha,15alpha-bis(tetrahydropyranyloxy)-16-phenoxy-5-cis-13-trans-omega-tetranorprostadienamide (XIV), which is then oxidized with the Jones reagent in acetone to the keto compound (XV). Finally, this compound is deprotected with acetic acid.
