In detail, a method of synthesizing an ortho-functionalized benzenesulfonyl fluoride derivative, the method comprises (a) reacting a benzenesulfonyl fluoride derivative represented by structural formula 1 with an organolithium represented by structural formula 2, thus synthesizing an intermediate represented by structural formula 3 in reaction scheme 1 and (b) reacting the intermediate with an electrophile, thus synthesizing a compound represented by structural formula 4 or a compound represented by structural formula 4′. The present disclosure enables the synthesis of several functionalized sulfonyl fluorides within a few seconds under mild temperature conditions in addition to the chemistry of Sulfonyl Fluoride Exchange (SuFEx), which is a next-generation click chemistry, so that sulfonyl fluoride, the main reactant of the SuFEx reaction, can be efficiently secured.

The incorporation of electron-deficient aryl sulfate diesters in the early stage of the synthesis of glycans, peptides, and the like, disclosed herein avoids time-consuming protecting group manipulations, simplifies the purification of sulfated products, and improves the overall yield and efficiency. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
