Mild but Efficient Methods for Stereoselective Glycosylation with Thioglycosides: Activation by [N-Phenylselenophthalimide-Mg(ClO4)2] and [PhIO-Mg(ClO4)2]

All articles of this category Combinations of N -phenylselenophthalimide (N-PSP) or iodosobenzene (PhIO) with Mg(ClO 4 ) 2 effectively promote glycosylation with thioglycosides under mild conditions. A 2,2,2-trichloroethoxycarbonyl group or trityl protecting group at the 6-position increased α-selectivity on glycosylation with 2- O -benzylated donors. glycosylation - thioglycoside - N -phenylselenophthalimide - iodosobenzene
