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.
