The invention relates to a method for preparing an oxazolidinone intermediate. Specifically, a synthesis procedure for the intermediate comprises: directly performing a “one-pot” reaction on a compound I, compound J or compound L without performing isolation, wherein a salt of a compound K is selected from a hydrochloride, sulfate, malate, tartrate, p-toluenesulfonate, or lactate, and wherein the symbol * in a compound indicates an atom of an R-type chirality or an S-type chirality or a racemate thereof.
这项发明涉及一种制备恶唑烷酮中间体的方法。具体而言,中间体的合成过程包括:在不对化合物I、化合物J或化合物L进行隔离的情况下,直接进行“一锅法”反应,其中化合物K的盐选自盐酸、硫酸、苹果酸、酒石酸、对甲苯磺酸或乳酸,并且化合物中的符号*表示R型手性原子或S型手性原子或它们的外消旋混合物。
