Yield:99-75-2 75% ,106-44-5 15%

Reaction Conditions:

with diphenyl diselenide;dihydrogen peroxide at 50; for 2 h;Green chemistry;

Steps:

3.3. General Procedure for the Synthesis of Esters 6
General procedure: Diphenyl diselenide (3, 0.006 g; 0.02 mmol) was treated with H2O2 (30%·w/w, 0.15 mL, 1.5 mmol)and stirred at room temperature until the discoloration of the reaction mixture. Then, the aldehyde 1(1 mmol) and the appropriate alcohol (2.5 mmol) were added. The reaction mixture was stirred at50 °C for 2 h and extracted three times with EtOAc (3 × 20 mL). The collected organic layers were driedover Na2SO4 and the solvent evaporated under reduced pressure.
