Ring expansion of N-acetyl aziridine-2-imides to oxazoline-4-imides, useful precursors of pure β-hydroxy α-aminoacids

Optically active N-acyl aziridine 2-imides or α-carboxylates rearrange to oxazoline-4-imides or 4-carboxylates with high regio and stereo control. This ring expansion followed by mild hydrolisis allows the synthesis of enantiomerically pure β-hydroxy α-aminoacid precursors.
