Abstract

Results reveal that the reductive cleavage of anisylidene acetals by BH3/Bu2BOTf can selectively produce either regioisomer, simply by adjusting the reaction temperatures and reagent concentrations. Reductive ring opening at low temperatures is determined to be compatible with sensitive functional groups such as allyl and enol ethers and other ketals.

Abstract

Sulfated epitopes of [alpha]-glucosamine (GlcN sulfoforms) are prepared by using solid-phase synthesis as models of internal glucosamines within heparan sulfate. The fragmentation analysis has distinguished GlcN sulfoforms bearing the relatively rare 3-O-sulfate from isomers with the more common 6-O-sulfate.
