Several 1,2-diaroyl-3-arylaziridines were previously prepared conveniently and used in the preparation of 5-benzoyl-2,4-diaryl oxazolines in the presence of NaI. In this work, synthesis of some trans-4-benzoyl-2,5-diaryl oxazolines by a regio- and stereo-controlled reaction in the presence of Iron (III) nitrate at room temperature is reported. A plausible mechanism has been proposed for ring expansion of N-acyl aziridines to oxazolines.
预先方便地制备了几种1,2-二芳酰基-3-芳基氮丙啶,并用于在NaI存在下制备5-苯甲酰基-2,4-二芳基恶唑啉。在这项工作中,报道了在硝酸铁 (III) 存在下在室温下通过区域和立体控制反应合成了一些反式-4-苯甲酰基-2,5-二芳基恶唑啉。已经提出了一种将 N-酰基氮丙啶扩环为恶唑啉的合理机制。
