摘要：

Reactions of dimethyl acetylenedicarboxylate with 3‐methylindole and 2,3‐dimethylindole under boron trifluoride‐diethyl ether catalysis were carried out at low temperature (0–25°). Thermally unstable cyclobutenes were isolated, mainly in apolar solvents, which isomerized to benzazepines. The other compounds isolated were Michael adducts and dihydro‐2‐oxocarbazoles.
