3, 6-O-BRIDGED PYRANOSE INVERSION COMPOUND AND PROCESS FOR PRODUCING B-O-PYRANOSIDE
An object of the present invention is to provide a 3,6-O-bridged pyranose-inverted compound useful for being easy to produce beta-O-pyranosides selectively. The 3,6-O-bridged pyranose-inverted compound according to the present invention is represented by General Formula (1): wherein RA and RB each represent hydrogen or are bonded to each other to form a benzene ring
one of RC and RD represents hydrogen and the other represents -OR2
R1 represents hydroxy or halogen
and R2 and R3 each represent a hydroxy-protecting group.
