YieldReaction ConditionsOperation in experiment
92% With 2,4,6-tripropyl-1,3,5,2,4,6-trioxatriphosphinane-2,4,6-trioxide; triethylamine; In acetic acid butyl ester; ethyl acetate; at 120℃; General procedure: T3P mediated synthesis of coumarins: To a mixture of 2-hydroxyaryl aldehyde/ketone (1, 0.01 mol) and appropriate acetic acid (2, 0.01 mol) in n-BuOAc (10 mL) was added T3P (0.02 mol, 50% soln in EtOAc) followed by triethylamine (0.02 mol). The resulting reaction mixture was stirred at 120 C for 6-10 h under conventional heating. When the reaction was completed (monitored by TLC), the mixture was cooled and washed with saturated NaHCO3 solution (1 × 10 mL), water and brine. The organic phase was dried over anhydrous Na2SO4. The solvent was removed under reduced pressure and the crude product was passed through a small plug of silica to afford the coumarins (3) in good purity and yield.
