The synthesis of sulfochromeno [4,3-b] pyrrolidines is described. Under the catalysis 20 mol% Brønsted base and using 4Å molecular sieves as HF scavenger, imines derived from salicylaldehydes diethyl aminomalonate react with ethenesulfonyl fluorides through a tandem [3+2] cyclization-SuFEx click reaction to produce in high yields.

Abstract Chemoselective transformations of functionalized sulfonyl fluorides and chlorides are surveyed comprehensively. It is shown that provide an excellent selectivity control in their reactions. Thus, numerous conditions tolerated by the SO 2 F group – from amide ester formation to directed ortho ‐lithiation transition‐metal‐catalyzed cross‐couplings. Meanwhile, sulfur (VI) fluoride exchange (SuFEx) also compatible with functional groups, thus confirming its title “another click reaction”. On contrary, a few exceptions, most typically occur at Cl moiety.
