合成路线1
该中间体在本合成路线中的序号：(XIII)The tetrahydrofuran intermediate (XX) has been obtained as follows: The reaction of (2S,3S)-epoxygeraniol (XII) with Bn-Br and NaH in THF gives the benzyl ether (XIII), which is treated with NaClO4 to yield the diol (XIV). The selective monoacetylation of (XI) with Ac2O and pyridine affords the monoacetate (XV), which is cyclized by means of (CF3CO2)ReO3 and TFAA to provide the tetrahydrofuran (XVI). The acetylation of the tertiary alcohol of (XVI) with Ac2O and Sc(OTf)3 gives the diacetate (XVII), which is debenzylated with H2 over Pd/C to yield the primary alcohol (XVIII). The oxidation of (XVIII) with DMP affords the carbaldehyde (XIX), which is finally condensed with iodoform and CrCl2 to furnish the target iodovinyl-tetrahydrofuran intermediate (XX).
