LAH reduction of dibenzo[a.c.]cycloheptadien-6-one oxime (Ib) in refluxing THF gives an aziridine,5,6-imino-dbenzo[a.c.]cycloheptadiene (IIa), in good yield together with a small amount of the expected primary amine, 6-amino-dibenzo[a.c.]cycloheptadiene (IIIa). The structure of the aziridine has been established by a reliable synthesis through an addition of iodine isocyanate to dibenzo[a.c.]cyclo-heptatriene
在回流的THF中用LAH还原二苯并[ac]环庚二烯-6-肟(Ib),得到氮丙啶5,6-亚氨基-d-苯并[ac]环庚二烯(IIa),收率很高,并有少量预期的伯胺胺,6-氨基-二苯并[ac]环庚二烯(IIIa)。通过将异氰酸碘加到二苯并[ac]环-庚三烯(V)中,可以可靠地合成氮丙啶的结构。氮丙啶与酸的开环反应已经进行。氮丙啶的产率取决于反应中使用的溶剂和温度。
