Heating the 1-alkynylpyrano[3,4-b]indol-3-ones (3), (5), and (7) results in intramolecularDiels-Alderreaction to the indole-2,3-quinodimethane diene with subsequent extrusion of carbon dioxide to give the cycloalka[a]carbazoles (4), (6), and (8).
加热1-炔基吡喃并[3,4- b ]吲哚-3-酮(3),(5)和(7)导致分子内Diels-Alder反应生成吲哚-2,3-喹二甲烷二烯,随后挤出二氧化碳,得到cycloalka [一个]咔唑(4),(6)和(8)。
