Abstract Methyl 2,3-di-O-acetyl-α,β-d-xylofuranoside was prepared as the sole regioisomer in 63–72% yield, according to the applied mass of substrate, through a Candida antarctica lipase B catalysed alcoholysis of methyl 2,3,5-tri-O-acetyl-α,β-d-xylofuranoside. The product is a potential synthetic precursor for 5-modified xylofuranosides and 5′-modified xylonucleosides.
摘要 根据应用的底物质量,通过南极念珠菌脂肪酶 B 催化醇解甲基,以 63-72% 的产率制备了甲基 2,3-二-O-乙酰基-α,β-d-呋喃木糖苷作为唯一的区域异构体。 2,3,5-三-O-乙酰基-α,β-d-呋喃木糖苷。该产品是 5-修饰的呋喃木糖苷和 5'-修饰的木糖核苷的潜在合成前体。
