Abstract

The transition-metal-catalyzed cyclization of 1, 6-enynes is one of the most convenient and efficient methods for the synthesis of a variety of carbocyclic and heterocyclic compounds.[1– 4] By this approach, enynes can be transformed into cyclic skeletons in a one-pot fashion with impressive regioand stereoselectivity.[3, 5, 6] The readily available and inexpensive metal nickel stands out for its remarkable power in catalyzing cycloisomerization and ...
