A simple enzymatic methodology for the selective monoacetylation of 1,n-diols (n=5,8) using vinyl acetate is reported. Monoacetylation excesses of 81–87% at 74–90% 1,n-diol conversions were obtained in toluene and diisopropyl ether using Thermomyces lanuginosus lipase (TLL) immobilised on polypropylene powder as catalyst.
报道了一种使用乙酸乙烯酯选择性地将1,n-二醇(n = 5,8)进行单乙酰化的简单酶学方法。在74-90%1处,使用固定在聚丙烯粉末上的嗜热霉菌脂肪酶(TLL)在甲苯和二异丙醚中获得单乙酰化率超过81-87%的n-二醇转化率。
