Abstract

A nickel-catalyzed protocol for the cycloisomerization of 1,6-dienes has been developed. Using commercially available NiBr₂ and PPh₃ as catalysts, Zn as a reductant, and ZnI₂ as an additive, the methodology efficiently converts various 1,6-dienes into pyrrolidine derivatives in excellent yields and high selectivity.
