Base-mediated synthesis of benzimidazole-fused 1, 4-benzoxazepines via sequential intermolecular epoxide ring-opening/intramolecular SNAr reactions

R Devi, S Mukhopadhyay, AJ Das, SK Das - Tetrahedron Letters, 2020 - Elsevier
We have developed a transition-metal-free, practical route to benzimidazole-fused 1, 4-
benzoxazepines. Operationally, the protocol involves a K 2 CO 3-mediated intermolecular …
