Studies on the alkylation of enolates derived from a range of N-acyl-5,5-dimethyloxazolidin-2-ones and N-acyl-5,5-diphenyloxazolidin-2-ones reveal that high yields and high diastereoselectivities are best obtained when homochiral 4-isopropyl-5,5-dimethyloxazolidin-2-one is employed as a chiral auxiliary.
对多种N-酰基-5,5-二甲基
噁唑啉-2-酮和N-酰基-5,5-二苯基
噁唑啉-2-酮衍生的烯醇负离子的烷基化研究表明,当使用手性辅助剂4-异丙基-5,5-二甲基
噁唑啉-2-酮时,可以获得高产率和高的立体选择性。
