Photoinduced intramolecular electron transfer in 3-benzylazaprop-1-enes is inhibited by N-acetyl or N-carbomethoxy protecting groups: fluorescence is then observed from the arene chromophore and intramolecular meta photocycloaddition occurs to give the linear azatriquinane system with high selectivity.
N-乙酰基或N-羰甲氧基保护基团抑制了3-苄基氮杂-1--1-烯中光诱导的分子内电子转移:然后从
芳烃发色团观察到荧光,并且发生分子内间光环加成反应,从而形成具有高选择性的线性氮杂三喹烷体系。
