Abstract

A methodology is described for the highly efficient and divergent synthesis of pseudosugars which allows the stereoselective introduction of polar groups at either the α or the β pseudoanomeric positions. Using this method, a series of 3-deoxycarbasugar analogues of mannose bearing a pyridyl group are rationally designed, prepared and tested for inhibition of Golgi α-mannosidase II.

Keywords: Carbasugar, Golgi mannosidase II, molecular modelling, synthesis.
