発明の名称 （英語） 3, 6-O-bridged pyranose inversion compound and process for producing B-O-pyranoside
発明の概要（英語） (US8445652)
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.
