Ethanol → HCID 53961628, compound

Participants

Reaction Steps

A solution of 4- formyloxy-3-hydroxy-1-butene (1.06 g, 10 mmol) and propionic acid (1 drop) in triethylorthoacetate (6 g, 40 mmol) was heated at 140° C. under conditions for distillative removal of ethanol. After 2H, the excess of ethylorthoacetate was removed by distillation in vacuo. The residue was hydrolysed with water and extracted with AcOEt. The product was purified by flash chromatography on SiO2 (eluant AcOEt: hexane, 2:8) (1 g, 60%) but distillative purification is preferred when larger quantities are involved.
