Abstract

The aza-Darzens (‘ADZ’) reactions of N-diphenylphosphinyl (‘N-Dpp’) imines with chiral enolates derived from oxazolidinones and camphorsultam have been studied. Whilst oxazolidinone enolates reacted poorly in terms of aziridination, the use of the chiral enolate derived from both antipodes of N-bromoacetyl 2,10-camphorsultam, 2R-(5) and 2S-(5), with N-diphenylphosphinyl aryl and tert-butylimines proceeded in generally good yield to give, respectively, (2′R,3′R)- or (2′S,3′S)-cis-N-diphenylphosphinyl aziridinoyl sultams of high de.
