An efficient asymmetric synthesis of isofagomine, based on a precursor containing three differentiated hydroxyl functions, is described. The side product in the key alkylation step is converted into (2S,3R,4R)-2,4-bis(hydroxymethyl)-3-hydroxypyrrolidine, a new C6 pyrrolidine azasugar, which inhibits α-glucosidase from yeast.
描述了一种高效的不对称合成异法戈敏的方法,该方法基于一种含有三个不同羟基功能的前体。在关键的烷基化步骤中,副产物转化为(2S,3R,4R)-2,4-双(羟甲基)-3-羟基吡咯烷,这是一种新的C6吡咯烷氮糖,能够抑制酵母中的α-葡萄糖苷酶。
