Synthesis of Novel 7‐methylene‐6,7‐dihyrobenzo[f]Benzo[4,5]Imidazo[1,2‐d][1,4]Oxazepines via Base‐mediated Regioselective Intramolecular Hydroamination

Synthesis of Novel 7‐methylene‐6,7‐dihyrobenzo[f]Benzo[4,5]Imidazo[1,2‐d][1,4]Oxazepines via Base‐mediated Regioselective Intramolecular Hydroamination

A versatile and transition metal‐free approach for the synthesis of new 7‐methylene‐6,7‐dihyrobenzo[f]benzo[4,5]imidazo[1,2‐d][1,4]oxazepines were developed by an efficient 7‐exo‐dig regioselective hydroamination of 2‐(2‐(prop‐2‐yn‐1‐yloxy)phenyl)‐1H‐benzo[d]imidazole in the presence of potassium ca...

Zusammenfassung:A versatile and transition metal‐free approach for the synthesis of new 7‐methylene‐6,7‐dihyrobenzo[f]benzo[4,5]imidazo[1,2‐d][1,4]oxazepines were developed by an efficient 7‐exo‐dig regioselective hydroamination of 2‐(2‐(prop‐2‐yn‐1‐yloxy)phenyl)‐1H‐benzo[d]imidazole in the presence of potassium carbonate in DMF at 90°C.
