Studies towards the total synthesis of repeating unit of O-sulfated polysaccharide from marine bacterium Cobetia pacifica KMM 3878

Herein we report assembly of the appropriately protected trisaccharide repeating unit of Cobetia pacifica KMM 3878 O-sulfated polysaccharide. Our synthesis involves 3,4-O-pyruvilated galactose as the key building block which acts as a donor as well as acceptor in the construction of trisaccharide. We obtained the R isomer as a major stereoisomer in the pyruvilation reaction. The glycosylations proceeded with high stereo and regioselectivity.

Highly efficient and mild method for regioselective de-O-benzylation of saccharides by Co2(CO)8-Et3SiH-CO reagent system

[Chemical equation presented] A highly efficient and mild method for the de-O-benzylation of protected saccharides was developed by transforming terminal benzyl ethers Into silyl ethers using Co2(CO)8-Et 3SIH under 1 atm of CO. The method was successfully used for the de-O-benzylatlon of perbenzylated monosaccharides with various anomerlc protecting groups, as well as natural disaccharldes and trisaccharides such as sucrose, raffinose, and melezltose In good yields (>80%).

Synthesis of a potential tetrasaccharide ligand for E-selectin

A potential tetrasaccharide ligand for E-selectin, (Na+-O3SO-3)Galβ-(1→4) [Fucα-(1→3)]Glcβ-(1→6)Gal, an analogue of the ovarian cystadenoma glycoprotein tetrasaccharide fragment, was synthesized in a highly practical way.
