Sodium Propionate → HCID 13335395, compound

Participants

Reaction Steps

In the same apparatus as in Example 1, 2-allyl-3-hydroxy-3-methyl-4-cyclopentenone (15.2 g), propionic acid (60 ml) and sodium propionate (3 g) were charged and heated at 120° to 130° C. for 8 hours with agitation. After the completion of the reaction, propionic acid was evaporated off under reduced pressure. The residue was extracted with toluene (60 ml) and water (40 ml) and treated as in Example 1 to obtain 2-allyl-4-propionyloxy-3-methyl-2-cyclopentenone (19.7 g). Yield, 94.7%. B.P., 115°-120° C./0.1-0.2 mmHg.
