Chiral small molecules such as amino alcohols and their heterocyclic derivatives are useful building blocks for asymmetric synthesis and the preparation of biologically active compounds. Using a common starting material derived from carbohydrate, the (S)-3-hydroxy-γ-butyrolactone, we have synthesized several five-, six-, and seven-membered nitrogen-containing chiral heterocycles. These include (S)
手性小分子(例如氨基醇)及其杂环衍生物是非对称合成和生物活性化合物制备的有用组成部分。使用衍生自碳水化合物的常见起始物质(S)-3-羟基-γ-丁内酯,我们合成了几个五元,六元和七元含氮手性杂环。这些包括(S)-3-苄氧基吡咯烷,被保护的6-取代的吗啉-3-酮及其同源的1,4-氧杂ze-3-酮和6-三苯甲氧基甲基四氢-1,3-恶嗪-2-硫酮。这些手性小杂环是通过有效的环化反应由内酯合成的。在此报告了它们的合成和表征。 氨基醇-杂环-环化-内酯-手性库-不对称合成
