Outline of Final Research Achievements

For the establishment of a novel cancer malignancy diagnostic method that utilized core 2 oligosaccharide as a tumour marker, two kinds of carba-disaccharides 2 and 3 corresponding to the partial structure of core 2 oligosaccharide (branched trisaccharides) were targeted and the synthesis of the carbasugar acceptors and the sugar donors was examined.
As a result, as carba-sugar block, the synthesis of two kinds of carba- β-D-galactose acceptor 5 and 14 having a hydroxy group at anomeric position and carba-N-acetyl-β-D-glucose 35 were achieved. On the other hand, as sugar block, the synthesis of GalNAc donor 46 having a triflate group at 6-position was achieved in 11 steps. About the synthesis of GulNAc donor having a triflate group at 3-position, the inversion reaction of GalNAc derivative 48 is examining.
