Transesterification between acetylated and free carbohydrates
Transesterification reactions have been performed in systems in which both acyl acceptor and acyl donor are carbohydrates with the same skeleton. Basic catalysis proved to be much more efficient than nucleophylic catalysis. Partially acetylated sugar derivatives have been prepared by selective deacy...

| description |
Transesterification reactions have been performed in systems in which both acyl acceptor and acyl donor are carbohydrates with the same skeleton. Basic catalysis proved to be much more efficient than nucleophylic catalysis. Partially acetylated sugar derivatives have been prepared by selective deacylation of peracetylated glycosides, using transesterification between a peracetylated sugar and a non-protected carbohydrate. This method compares favourably with known regioselective acylation methods. |
