摘要：

[GRAPHICS] A 1:1 mixture of the (pi-allyl)palladium complex (eta(3)-C3H5)Pd(Cl)PCy3 and NaB[3,5-C6H3(CF3)(2)](4) in the presence of HSiEt3 catalyzed the cycloisomerization of functionalized 1,6-dienes to form 1,2-disubstituted cyclopentenes in good yield with high selectivity (typically >94%). The protocol tolerated a range of functional groups and substitution at one of the allylic carbon atoms.
