Abstract The acid-catalysed acetonation of D -glucitol has been studied in detail. The true complexity of the reaction, giving the 1,2- and 3,4-monoacetals, the 1,2:3,4-, 3,4:5,6-, and 1,2:5,6-diacetals, and the 1,2:3,4:5,6-triacetal, has been shown. These studies have been carried out mainly by gas-liquid chromatographic techniques, and have shown that, with acetone, the primary hydroxyl group at
摘要对D-葡萄糖醇的酸催化丙酮化进行了详细的研究。反应的真正复杂性,即得到1,2-和3,4-单缩醛,1,2:3,4-,3,4:5,6-和1,2:5,6-二缩醛,并显示了1,2:3,4:5,6-三缩醛。这些研究主要是通过气相色谱技术进行的,结果表明,使用丙酮时,C-1处的伯羟基比C-6处的伯羟基更具反应性。各种缩醛的结构已通过pmr光谱法验证。
