Intramolecular N-nitrene addition in 2-(hepta-1,6-diene-4-yl)-3-aminoquinazolone derivatives gives aziridines stereospecifically in good yield; the regio-specificity (or lack of it) is rationalised in terms of a non-concerted addition proceeding by electrophilic attack of the nitrene on the alkene double bond via a 7-membered transition state.
在2-(庚-1,6-二烯-4-基)-3-氨基喹唑啉酮衍生物中分子内添加N-硝烯可形成立体特异性的氮丙啶,收率高。区域专一性(或缺乏区域专一性)是通过无约束的加成反应而合理化的,该加成反应是通过7元过渡态对烯类双键进行氮亲电攻击。
