Hydroxymethyl C-glycoside

Frechou, C, Dheilly, L, Beaupere, D, Demailly, R U, Reaction of sulfur ylides on reducing sugars application to the synthesis of hydroxymethyl C-glycosides, Tetrahedron Lett, 33, 5067-5070, 1992. [Pg.359]

The reaction of methyl 2,3,4,6-tetra-O-benzyl-a-D-glucopyranoside or -manno-pyranoside with triethylsilane-Tms triflate gave the corresponding 1,5-anhydro-hexitols, which can be viewed as hydroxymethyl-C-glycosides of P-l-xylopyranose and a-D-arabinopyranose, respectively. ... [Pg.227]

Such an attraction would overcome, at least in part, the conformational instability imposed by the erected oxygen atom. For pyranosides which are not deoxygenated at C-6, the added electron-withdrawing power of the hydroxymethyl (or acyloxymethyl) group at C-5 should increase the charge on C-5, thus favoring a-D-glycoside formation even more.M(b)... [Pg.301]
