Acetamidoglycosylation with Glycal Donors: A One-Pot Glycosidic Coupling with Direct Installation of the Natural C(2)-N-Acetylamino Functionality.
ABSTRACT Nitrogen transfer to glycals: A new method for direct C2-aza-glycosylation with glycal donors has been developed (see scheme), employing the new reagent combination of thianthrene-S-oxide and trifluoroacetic anhydride for glycal activation, in an overall one-pot procedure.

ABSTRACT: The direct stereoselective I111-mediated ocidative ring contraction of a protected 6-deoxy-D-gulal substrate to form a highly functinalized tetrahydrofurfural intermediate is a key step in the first total synthesis of (+)-pyrenlide D (see scheme; R = TBS = tert-butyldimethylsilyl).Angewandte Chemie International Edition 03/2001; 40(6):1128 - 1130.
