Abstract
The use of epoxides obtained by dimethyldioxirane epoxidation of y-4,5 :7,8-di-O-isopropylidene-D-manno-oct-1-enitol as glycosyl donors is de scribed. This method offers a simple and stereoselective access to pre cursors of Kdo glycosides. The stereochemical outcome of the reaction is rationalized by means of semiempirical calculations of the transiti on states leading to glycosides formation.
