摘要:This invention relates to reagents and methods for synthesis of biologically active di- and tri-saccharides comprising α-D-Gal(1→3)-D-Gal. In particular the invention provides novel reagents, intermediates and processes for the solution or solid phase synthesis of α-D-galactopyranosyl-(1→3)-D-galactose, and derivatives thereof. In one preferred embodiments the invention provides a protected monosaccharide building block of general formula (II): in which R 3 is methoxy or methyl; R 1 is H, benzoyl, pivaloyl, 4-chlorobenzoyl, acetyl, chloroacetyl, levulinoyl, 4-methylbenzoyl, benzyl, 3,4-methylenedioxybenzyl, 4-methoxybenzyl, 4-chlorobenzyl, 4-acetamidobenzyl, or 4-azidobenzyl; and R 2 is H, Fmoc, benzoyl, pivaloyl, 4-chlorobenzoyl, acetyl, chloroacetyl, levulinoyl, 4-methylbenzoyl, benzyl, 3,4-methylenedioxybenzyl, 4-methoxybenzyl, 4 -chlorobenzyl, 4-acetamidobenzyl, or 4-azidobenzyl.
