A palladium-catalyzed regio- and diastereoselective diarylation of glycals and pseudoglycals, which is a kind of Heck-Suzuki arylation, is described. A wide range of arylboronic acids reacted under these conditions smoothly. Selectivity was C1-C2(α,α) in
SYNTHESIS OF (2-DEOXY-α-D-GLYC-2-ENOPYRANOSYL)ARENES BY STEREOSPECIFIC CONJUGATE-ADDITION OF ORGANOCOPPER REAGENTS TO PERACYLATED HEX-1-ENOPYRAN-3-ULOSES

The reaction of peracylated 1,5-anhydro-2-deoxyhex-1-eno-uloses with higher-order cyanoorganocuprate in oxolane at low temperature in the presence of acetic anhydride afforded the corresponding glycosylarenes in good yields.A complete stereocontrol could
Arylation de glycals catalysee par les sels de palladium: nouvelle synthese de C-glycosides

The arylation of peracetylated glycals catalyzed by palladium salts provides a new synthesis of C-glycosides.The title reaction is applied to several aromatic compounds, including fluoro and nitro derivatives.The regioselectivity of the reaction with respect to the aromatic nucleus is explained by the formation of an arylpalladium directly from the aromatic compound and the salt.A two-step mechanism, involving syn-addition of the arylpalladium to the glycal double bond, followed by a syn-elimination is proposed and discussed.
