Abstract
Lewis-acid mediated heterolysis of substituted methoxy acetals derived from anomeric [3.3.1] oxabicyclic lactones leads to enantiopure deoxy C-glycosi des in excellent chemical yield. An alternative route to C-glycosidic ester s involves simple one-step opening of [3.3.1] oxabicyclic lactones with in situ esterification. (C) 1999 Elsevier Science Ltd. All rights reserved.
