Methyl 6-O-butyryl-α-D- and -L-galactopyranoside and methyl 6-O-butyryl-α-D- and -L-mannopyranoside, which present three contiguous secondary hydroxy groups in different orientations, have been acylated using three hydrolytic enzymes. Porcine pancreatic, Candida cylindracea, and Pseudomonas fluorescens lipases in organic solvents. Some generalization of the obtained results is discussed.
甲基6-O-丁酰基-α-D-和-L-吡喃半乳糖苷和甲基6-O-丁酰基-α-D-和-L-甘露吡喃糖苷,它们以不同的方向呈现三个连续的仲羟基,已使用三种方法酰化水解酶。在有机溶剂中的猪胰腺,念珠菌和荧光假单胞菌脂肪酶。讨论了所得结果的一些概括。
