A new cycloisomerisation of Z-1-iodo-4-N-methylbenzenesulfonyl-1,6-enynes to functionalized pyrroles was realized in the presence of an organomolecule (4,4′-bis(1,1-dimethylethyl)-2,2′-bipyridine) and KOtBu.

A highly efficient palladium‐catalyzed cascade metallo‐ene/metallo‐carbene coupling reaction was developed to produce 2,3‐dihydropyrrole derivatives in high yields. In this transformation, two new Csp3−Csp2 and Csp2−Csp2 bonds were constructed in one‐pot. The alkene was one of the most easily functionalized groups, making it possible for these molecules to be transformed into more complex molecules. More importantly, the final product possessed an attractive 1,3,8‐trienes scaffold, which was difficult to be synthesized.
