A microwave assisted phase transfer catalyzed transesterification in basic medium with methyl benzoate was studied for several carbohydrates. Small amounts of DMF were necessary to provide good yields (96-76%) within 15 minutes. This method was extended to the synthesis of dodecanoyl derivatives with 63–100% global yields within 15 to 30 minutes. Rate enhancements when compared to conventional heating
