Abstract

Enantioselective and diastereoselective alpha-D-glucosylation of 2,3-O-isopropylidene-erythritol was observed in transglucosylation with a synthetic donor using three kinds of immobilized isomaltulose-producing microorganisms. Several related compounds, including an 2,3-O-isopropylidenated aldotetrose dimethyl dithioacetal and an aldotetronic acid ester were also glucosylated in moderate or good yield, depending on the microorganism utilized. Steric as well as functional group factors are discussed in relation to the substrate specificity of the glucosyl acceptor.
