title: Synthesis of the monodeoxy derivatives of 2-(trimethylsilyl)ethyl beta-lactoside.
abstract: Monodeoxy derivatives of 2-(trimethylsilyl)ethyl (Me3SiEt) beta-lactoside were synthesized, by deoxygenation at the disaccharide level, for the 2'-, 3'-, 4'-, and 6'-monodeoxylactosides. The 2-, 3-, and 6-deoxy derivatives were synthesized by beta-D-galactosylation of suitably protected monodeoxygenated Me3SiEt glucosides. Silver silicate was shown to be an efficient glycosylation promoter in the preparation of the 2- and 3-deoxylactosides.
