摘要：

The pyridazino[4,5-b]indole (3), which is conveniently available from 3-methylthioindole and the tetrazine (2), undergoes thermally induced inverse-electron-demand Diels-Alder reactions with enamines to afford the cycloalkene-annelated carbazoles (7,8) or the 2-substituted carbazole (9), respectively.
