method for the synthesis of alcohols from the corresponding carboxylic acids is described. Activation of carboxylic acid with 1-propanephosphonic acid cyclic anhydride (T3P) and subsequent reduction using NaBH4 yield the alcohol in excellent yields with good purity. Reduction of several alkyl/aryl carboxylic acids and Nα-protected amino acids/peptide acids as well as Nβ-protected amino acids was successfully
描述了一种由相应的羧酸合成醇的简单有效的方法。用1-丙烷膦酸环酐(T3P)活化羧酸,然后使用NaBH 4还原,可得到纯度高,纯度高的醇。的减少几个烷基/芳基羧酸和N α -保护的氨基酸/肽酸以及如N β -保护的氨基酸被成功地执行,以获得良好的收率相应的醇。所有产物均通过1 H NMR和质谱分析充分表征。该过程温和,简单,并且容易分离产物。
