Functionally Substituted Vinyl Carbanions, 43. Convenient Transformation of Hexopyranosides into α-Methylene δ-Lactone Derivatives

Treatment of glycopyranosyl phenyl sulfoxides 2ah, l, 2bh, l with two equivalents of lithium diisopropylamide provides directly the C-2-lithiated glycal intermediates 3aAh, l, 3bAh, l which, on reaction with formaldehyde as electrophile, furnish the 2-hyd

DIRECT LITHIATION OF GLYCALS. SYNTHESIS OF C-2 BRANCHED SUGARS

Direct lithiation at the C-2 atom of 1-phenylsulfinyl substituted glucals 4a,b can be readily performed with LDA as indicated by reactions of different C-electrophiles.Ohenylsulfinyl group removal takes place in the aldehyde reaction products by simple th
