A glycosyl donor represented by formula (I) is used for preparing an S-glycoside compound represented by formula (III), an O-glycoside compound represented by formula (V), and a C-glycoside compound represented by formula (V). The glycosyl donor is a raw material in the preparation of O-glycoside, S-glycoside, and C-glycoside compounds by means of a free radical reaction, most of which have a special α configuration.
An object of the present invention is to provide a novel substance that has a high reactivity as a fluorinating agent, is effectively used in various fluorination reactions, and is safely handled even in air. As the solution for achieving this object, the present invention provides a complex obtained by reacting bromine trifluoride with at least one metal halide selected from the group consisting of halogenated metals and halogenated hydrogen metals in a nonpolar solvent. This complex serves as a fluorinating agent that provides excellent fluorination performance and that is stable in air.

The invention relates to silanizing agents comprising a saccharide end group and to the use thereof for the functionalization of solid supports. The invention also relates to solid supports that have been functionalized by said silanizing agents (glycochips) and to the use of same, such for biological analysis and, in particular, for screening saccharide molecules or proteinaceous ligands of interest.
