A concise chemoenzymatic synthesis of glucose 6-phosphate is described. Candida rugosa lipase was found to be an efficient catalyst for both regio- and stereoselective deacetylation of the primary hydroxy group in the peracetylated D-glucose. In addition, we report an improved synthesis of 1,2,3,4,6-penta-O-acetyl-α-D-glucopyranose providing a large-scale procedure for the acetylation of α-D-glucose
描述了葡萄糖 6-磷酸的简明化学酶法合成。发现假丝酵母脂肪酶是全乙酰化 D-葡萄糖中伯羟基的区域和立体选择性脱乙酰化的有效催化剂。此外,我们报告了 1,2,3,4,6-penta-O-乙酰基-α-D-吡喃葡萄糖的改进合成,提供了一种大规模的 α-D-葡萄糖乙酰化程序,而无需在异头异构化中央。高总产率和易扩展性使这种化学酶促策略对工业应用具有吸引力。此外,用于酶促水解步骤的膦酸酯过渡态类似物的分子模型支持用假丝酵母脂肪酶观察到的底物选择性。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
