biologically potent and novel 1-deoxythiosugars is accomplished. Introduction of sulfur mediated by benzyltriethylammonium tetrathiomolybdate, as a sulfur transfer reagent through nucleophilic double displacement of tosylate in alpha,omega-di-O-tosyl aldonolactones in an intramolecular fashion is the key feature. The subsequent reduction of thiosugar lactones with borohydride exchange resin (BER) offers a
完成了有效且新颖的具有生物活性的新型1-脱氧硫糖的化学合成。通过硫代甲酸酯以α,ω-二-O-甲苯磺酰基内酯内酯的亲核双取代以分子内方式引入作为硫转移剂的苄基三乙基铵四硫代钼酸铵是主要特征。随后用硼氢化物交换树脂(BER)还原硫糖内酯可提供许多脱氧硫糖,总收率良好。
