4,6-Dimethoxy-2,3-diphenylindole 1 undergoes reaction with formanilide, acetanilide, benzanilide and several dimethoxy analogs in the presence of phosphoryl chloride to give the corresponding 7-imino derivatives 2–6. This reaction has been extended to include the synthesis of 7-indolyl-pyrrolines and tetrahydropyridines 7–9, 11 and oxazolines 14,15.

The pharmacological effectiveness of indoles, benzoxazepines and benzodiazepines initiated our synthesis of indole fused benoxazepine/benzodiazepine heterocycles, along with enhanced biological usefulness of the fused rings. Activated indoles 5, 6 and 7 were synthesized using modified Bischler indole synthesis rearrangement. Indole 5 was substituted with the trichloroacetyl group at the C7 position, yielding
