Abstract

We report an efficient one-pot synthesis of a novel series of chromenopyridodiazepinone polyheterocycles by a catalyst-free nucleo­philic addition of ethane-1,2-diamine to (E,E)-3-[3-(2-hydroxyphenyl)-3-oxoprop-1-en-1-yl]-2-styrylchromones at room temperature under mild conditions. The reaction proceeds by a tandem process involving 1,4- and 1,6-aza-conjugate additions of one amino group of ethane-1,2-diamine to the α,β-unsaturated (3-oxoprop-1-en-1-yl) and the α,β,γ,δ-diunsaturated (2-styrylchromone) carbonyl system of the precursor, followed by imine condensation of the remaining amino group to generate the chromenopyridodiazepinone polyheterocycle. All compounds were characterized by means of one- and two-dimensional NMR spectroscopy and single-crystal X-ray crystallography.

  • 13 Chromenopyridodiazepinones 2ac; General Procedure Ethane-1,2-diamine (10 mmol) was added to a stirred solution of the appropriate styrylchromone 1ac 12c (1 mmol) in THF (20 mL), and the mixture was stirred for 2 h at r.t. The solvent was removed under reduced pressure, and the resulting resinous material was subjected to short-plug silica-gel column chromatography. The product was crystallized from 1:1 hexane–CH2Cl2 by slow evaporation at 6 °C to afford bright-yellow crystals. Good-quality single crystals suitable for X-ray analysis were obtained for 2a and 2c only.
