Potassium Carbonate → 8-(Benzyloxy)-5-[(2S)oxiranylmethoxy]-3,4-dihydro-2(1H)-quinolinone

Participants

Reaction Steps

A mixture of 8-(benzyloxy)-5-hydroxy-3,4-dihydro-2(1H)-quinolinone (0.20 g, 0.743 mmol), (S)-(+)-glycidyl 3-nitrobenzenesulfonate (0.193 g, 0.743 mmol) and potassium carbonate (0.113 g, 0.817 mmol) in 2-butanone (10 mL) was heated at reflux for 16 hours. The solvent was removed in vacuo and the residue purified by flash chromatography (chloroform-methanol, 50:1) to yield the title compound (0.210 g, 0.61 mmol).
