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 exten

Lithium diphenylcuprate treatment of methyl 2,3-anhydro-4,6-O-benzylidene-D-pyranosides in which the anomeric substituent and the three-membered rings are cis oriented furnished the expected trans-diaxial opening products. When the relationship betwe
