A novel method of synthesizing trans-β-terpinyl esters based on selective elimination of one mole of carboxylic acid from trans-terpin-1,8 diesters with aliphatic acids C2 to C5 and benzoic acid has been described.Elimination reaction was carried out at temperature 120-190 deg C in media of acid anhydrides, in presence of sodium salt of the same acid.Terpinyl esters were obtained in 30-75percent yield.Selectivity of elimination has increased with increase in molecular weight of eliminated acid from 81percent for acetic to 94percent for n-pentanoic, and 95percent for benzoic.
