N -(2-Hydroxymethylphenyl)pyrrole is prone to selective a-metalation with fj-BuLi-potassium ferf-butoxide. Trapping the formed anion with a variety of electrophiles and treatment of the crude products with silica gel in toluene results in pyrrolo-benzoxazepines 266 and pyrrolo-benzoxazepinone 267 (Scheme 57 (1994T2071)).
