We report an asymmetric synthesis of (4S,5S)-2-oxo-4-phenyloxazolidine-5-carboxylic acid via stereoselective addition of phenylmagnesium bromide (PhMgBr) to an N-sulfinimine derived from (R)-glyceraldehyde acetonide. (S)- and (R)-Glyceraldehyde acetonides, important chiral synthons in synthetic organic chemistry, are prepared from the corresponding epichlorohydrin using an identical synthetic methodology
我们报告了不对称合成的(4 S,5 S)-2-氧--4-苯基恶唑烷-5-羧酸通过立体选择性地将苯基溴化镁(PhMgBr)加到衍生自(R)-甘油醛丙酮化物的N-亚磺胺中。(S)-和(R)-甘油醛丙酮化物是合成有机化学中重要的手性合成子,是使用相同的合成方法由相应的环氧氯丙烷制备的。
