A tandem reaction strategy for forming triquinanes from linear allenyl diazo compounds through an intramolecular 1,3-dipolar cycloaddition reaction of an allenyl diazo group that generates a trimethylenemethane (TMM) diyl followed by an intramolecular [2 + 3] TMM diyl cycloaddition reaction has been developed. The new tandem cycloaddition reaction is readily applicable to the synthesis of complex molecules
通过分子内 1,3-偶极环加成反应生成三亚甲基甲烷 (TMM) 二基,然后分子内 [2 + 3] TMM 二基环加成反应,通过分子内 1,3-偶极环加成反应从线性丙二烯基重氮化合物形成三喹烷的串联反应策略发达。新的串联环加成反应很容易适用于复杂分子的合成,具有高通用性和效率。
