Di-tert-butyl 4,7,10,13,16-pentaoxanonadecane-1,19-dioate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 0.4 g of sodium is added to a solution of 91 g of tetraethylene glycol in 250 ml of tetrahydrofuran, and the mixture is stirred at room temperature. Once the sodium has dissolved, 145 ml of tert-butyl acrylate are added. The mixture is stirred for 12 h. The reaction solution is neutralized with ammonium chloride, concentrated, taken up in aqueous sodium chloride solution and extracted with ethyl acetate. The organic phase is concentrated. The residue is 39. The mixture is stirred for 12 h concentrated extracted with ethyl acetate The organic phase is concentrated
