权利人:POSTECH RES & BUSINESS DEV FOUND
摘要:Disclosed are ultrafast flow synthesis of functionalized sulfonyl fluorides and subsequent SuFEx connections via lithiated chemistry. 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.
