4-(Methyl, phenyl, benzyl, and i-propyl)-5,5-dimethyl-oxazolidin-2-ones, readily available from α-amino acids, are shown to be effective chiral auxiliaries for stereoselective enolate alkylations and conjugate additions of attached N-acyl moieties.
4-(甲基,苯基,苄基,和我-丙基)-5,5-二甲基-恶唑烷-2-酮,可容易地从α氨基酸,被证明是有效的立体选择性为烯醇化物烷基化和的共轭加成的手性助剂连接的N-酰基部分。
