Various substituted taurines have been synthesized expeditiously and practically in satisfactory to good yields directly from amino alcohols using a two-step, one-pot procedure, in which the amino alcohols undergo sulfuric acid esterification and subsequent sodium sulfite substitution. Treatment of amino-substituted secondary alcohols using the same procedure gave 2-substituted or 1,2-di-substituted
使用两步一锅法直接从氨基醇中快速且实际地以令人满意的高产率合成各种取代的牛磺酸,其中氨基醇经历硫酸酯化和随后的亚硫酸钠取代。使用相同程序处理氨基取代的仲醇得到 2-取代或 1,2-二-取代的牛磺酸,表明在取代步骤期间形成了作为中间体的氮丙啶。该方法是制备结构多样的 2-取代和 1,2-和 2,2-二取代牛磺酸的最有效途径之一。
