of β-galactosides of nucleosides and acyclic nucleoside analogues has been developed, using β-galactosidase from Escherichia coli as a catalyst and lactose as a sugar donor. The method is very rapid, feasible and last but not least inexpensive. Its applicability has been proven for a broad variety of possible substrates with respect to its scaling up for preparative use. Five new compounds from a series
已经开发了一种新的酶法,用于合成核苷和无环核苷类似物的β-半乳糖苷,使用来自大肠杆菌的β-半乳糖苷酶作为催化剂,乳糖作为糖供体。该方法非常快速,可行并且最后但并非最不昂贵。就其用于制备用途的放大而言,其适用性已被证明可用于多种可能的基材。已经从几百毫克的规模制备了一系列核苷和无环核苷类似物的五种新化合物,在所有情况下,都显示出该方法关于反应产率的可再现性和纯化过程的简便性的非常好的结果。
