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.

摘要:Disclosed herein are heterocyclic arynes and methods for preparing the same. Heteroarynes such as 5-membered O- or N-heterocyclic arynes have been considered inaccessible due to ring strain associated with the triple bond. The methods described herein demonstrate that these arynes can be successfully prepared through the utility of pi-backbonding from a transition metal. Synthetic utility of this method has been demonstrated by the facile synthesis and functionalization of heterocycles using these heteroaryne building blocks.
