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
已经研究了N-二苯基次膦基(' N -Dpp')亚胺与恶唑烷酮和樟脑的手性烯醇的氮杂-Darzens('ADZ')反应。虽然恶唑烷酮烯醇化物在叠氮反应方面反应较差,但是使用衍生自N-溴乙酰基2,10-樟脑,2 R-(5)和2 S-(5)对映体的手性烯醇化物与N-二苯基膦基芳基和叔-butylimines在通常良好的产率进行,得到分别,(2' - [R,3' - [R )-或(2'小号,3'小号) -顺式-高de的N-二苯基亚膦酰基叠氮基磺酰基。
