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

4,6-Dimethoxy-2,3-diphenylindole (1) undergoes acylation, bromination, oxidative coupling and acid-catalysed addition to aldehydes at C-7 to produce a range of 7-substituted indoles (3–11), the indolo-isatin (6), the 7,7′-bi-indolyls (14), (16), (18), and the 7,7′-di-indolylmethanes (20–31). Addition to cyclopentanone gave compound (32), while Michael addition to α,β-unsaturated ketones gave compound
of pathogenic bacteria with MICs as low as 3.1 μM. A structureactivityrelationshipstudy identified the key structural components necessary for inhibition of both bacterial growth and transcription. Correlation of in vitro transcription inhibition activity with in vivo mechanism of action was established using fluorescence microscopy and resistance passaging using Gram-positive bacteria showed no
