enantiomeric pure α-amino-β-hydroxy acids, react with aryl- and alkyl sulphonyl chlorides in pyridine affording the corresponding optically active 2-alkyl-2-oxazoline-4-carboxyamido-N-sulphonyl derivatives without appreciable racemization.
衍生自对映体纯α-氨基-β-羟基酸的旋光的2-烷基-2-恶唑啉-4-羧酰胺与吡啶中的芳基和烷基磺酰氯反应,得到相应的旋光的2-烷基-2-恶唑啉- 4-羧酰胺基-N-磺酰基衍生物,没有明显的外消旋作用。
