Abstract
Conjugate addition of silyl cuprates 1a,b and lithio trialkyl stannanes 1c,d to monosaccharide-derived 2,3-dihydro-4H-pyran-4-ones 2-5 and 10 constitutes a new entry to silyl- and stannyl glycosides 6-9 and 11-13 which either may be employed for the Sila-Baeyer-Villiger oxidation to give pyranoses or are potential precursors for C-glycosides. The keto functionality in 8a/13a can efficiently be reduced to the alcohol in 14a or methylated to form 15 without affecting the anomeric silyl- or stannyl group.
