An Efficient Microwave-Assisted Propylphosphonic Anhydride (T3P^®)-Mediated One-Pot Chromone Synthesis via Enaminones

Abstract

An efficient synthesis of 4H-chromene-4-ones via enamino ketones, with cyclization by using T3P^® under microwave heating is described. This is the first report for the synthesis of chromones by using T3P^®. Significant features of this method include short reaction times and high-purity products.

Keywords

cyclization - chromenones - enamino ketones - propylphosphonic anhydride - microwave heating - hydroxybenzophenones

• 28 6-(1,3-Benzodioxol-5-yl)-4H-chromen-4-one (3t); Typical Procedure A mixture of acetophenone derivative 1t (100 mg, 0.39 mmol) and (MeO)₂CHNMe₂ (0.051 mL, 0.39 mmol) was introduced into a 2–5 mL pressure-resistant vial, and the mixture was subjected to microwave irradiation for 10 min at 100 °C. The mixture was then cooled to RT, a 50% solution of T3P^® in EtOAc (0.25 mL, 0.39 mmol) was added, and the mixture was irradiated for a further 10 min at 90 °C until the reaction was complete (TLC; 30% EtOAc–PE). The crude mixture was diluted with EtOAc (10 mL) and washed with H₂O (5 mL) and brine (4 mL), then dried (­Na₂SO₄). After filtration and removal of the solvent, the crude product was purified by column chromatography (silica gel, EtOAc–hexane) to give a white solid; yield: 83 mg (80%); mp 177–179 °C.
