Iridium-catalyzed [3+2] cyclization of terminal alkynes with sulfoxonium ylides to construct 2,5-disubstituted furans.

A novel iridium-catalyzed [3+2] cyclization of sulfoxonium ylides with terminal alkynes for the synthesis of 2,5-disubstituted furans has been demonstrated. This protocol features a broad substrate scope, mild reaction conditions, and good to excelle…
