Cyclooctyne smoothly underwent 1,3-dipolar cycloaddition with pyridinium dicyanomethylides to afford the corresponding indolizines (8-cyario-7-azatricyclo[7.6.0.02,7]pentadeca-1,3,5,8-tetraenes) in excellent yields.
环辛炔与吡啶鎓二氰基甲基化物平稳地进行1,3-偶极环加成反应,从而以优异的收率得到相应的吲哚嗪类化合物(8-cyario-7-氮杂三环[7.6.0.0 2,7 ] pentadeca-1,3,5,8-四烯)。
