Direct 2,3-O-isopropylidenation of α-D-mannopyranosides and the preparation of 3,6-branched mannose trisaccharides.
A highly efficient, regioselective method for the direct 2,3-O-isopropylidenation of α-D-mannopyranosides is reported. Treatment of various α-D-mannopyranosides with 0.12 equiv of the TsOH·H2O and 2-methoxypropene at 70 °C gave 2,3-O-isopropylidene-α-D-mannopyranosides directly in 80%~90% yields. Based on this method, a 3,6-branched α-D-mannosyl trisaccharide was prepared in 50.4% total yield u...

متن کاملChemoenzymatic synthesis of α-dystroglycan core M1 O-mannose glycans.
The diversity-oriented chemoenzymatic synthesis of α-dystroglycan (α-DG) core M1 O-mannose glycans has been achieved via a three-step sequential one-pot multienzyme (OPME) glycosylation of a chemically prepared disaccharyl serine intermediate. The high flexibility and efficiency of this chemoenzymatic strategy was demonstrated for the synthesis of three more complex core M1 O-mannose glycans fo...
متن کاملThe role of mannose sensitive and mannose resistant pili of Escherichia coli in urinary tract infection
In order to study the relationship between hrmolysin / ashesins of Escherichia coli and occurrence of urinary tract infection ( UTI), the capacity of 570 isolated E.coli in agglutination of human or guinea pig erythrocytes and their lysis were tested. These isolates were obtained from the urine of patients with bacteriuria and from the stool of healthy people. Three patterns of hemagglutinat...
