Synthesis of anomerically pure, furanose-free α-benzyl-2-amino-2- deoxy-D-altro- and D-manno-pyranosides and some of their derivatives

Chiu, Tony M. K.,Sigillo, Katina,Gross, Paul H.,Franz, Andreas H.

, p. 2355 - 2381 (2008/02/10)

The anomerically pure benzyl α-d-glycoside of 2-amino-2-deoxy- mannopyranoside was synthesized from d-glucopyranose via 2-amino-2-deoxy-d- altrose intermediates. Unlike the direct synthesis from mannosamine in the literature, our method provides furanose-
