  Asymmetric synthesis of 5-isopropyl-oxazoline-4-imide as syn-hydroxyleucine precursor

  摘要：

  The synthesis of syn N-acetyl-hydroxyleucine methyl ester is reported through the ring expansion of aziridine-2-imides to oxazoline-4-imides. The key steps of the synthesis are the I,il-addition of O-benzylhydroxylamine to unsaturated imides, promoted by Lewis acids, and the regio- and stereoselective ring expansion of ti ans-aziridines to trans-oxazolines.
