合成路线1
该中间体在本合成路线中的序号：(XXV)3) The addition of the iodinated tetrahydofuranone (XXIV) to the triple bond of (XXIII) catalyzed by CuI and palladium tetrakis(triphenylphosphine) in triethylamine yields intermediate (XXV) with a double and a triple bonds that are hydrogenated with H2 over a rhodium triphenylphosphine complex in benzene/methanol affording the saturated tridecanol (XXVI). Finally, the double bond of the dihydrofuranone ring of uvaricin is formed by oxidation of the phenylsulfanyl group to the corresponding sulfonyl derivative with m-chloroperbenzoic acid in dichloromethane followed by elimination of benzenesulfonic acid by refluxing in toluene.
