Reaction of methyl- and phenylthiomethylidene phosphoranes 1 and 2 with a variety of reducing sugars has been explored. Furano-type carbohydrates afforded with good yields the corresponding open-chain vinyl sulfides, whereas pyrano derivatives produced elimination compounds together with the expected vinyl sulfides, depending on the nature of the protective groups.
已经研究了甲基和苯基硫代亚甲基膦烷1和2与多种还原糖的反应。呋喃诺型碳水化合物具有良好的收率,可提供相应的开链乙烯基硫化物,而吡喃衍生物则根据保护基团的性质与预期的乙烯基硫化物一起生成消除化合物。
