Abstract:
Four types of dehydroabietic acid-alcohol spice esters, i.e. dehydroabietic acid-cinamic alcohol ester, dehydroabietic acid-fenchol ester, dehydroabietic acid-borneol ester and dehydroabietic acid-menthol ester, were synthesized by O-acylation reaction of dehydroabietyl acyl chloride and alcohol spices using dehydroabietic acid as starting material. Suitable synthetic conditions of the target products were found to be as follows: reaction time 10 h, reaction temperature 95-100 ℃, molar ratio of reactants 1.2:1 (alcohol:chloride). The target products were characterized by means of IR, UV, NMR, and MS.
