Abstract

2H‐[1,3]Oxazino[3,2‐α]indolin‐4(3H)‐ones are easily prepared starting from indole and readily available 2‐methoxybenzoylchlorides by formation of the indole−acyl unit followed by a BBr3 deprotection/cyclization cascade.
A methodology for the synthesis of 2H‐[1,3]oxazino[3,2‐α]indolin‐4(3H)‐ones is reported. They are obtained from readily available materials by a facile synthetic procedure following either a two‐step cascade reaction or a step‐by‐step transformation. The target compounds represent a hitherto unreported class of indole derivatives with a novel kind of tris‐ or tetracyclic backbone.
