Abstract

The intramolecular cyclopropanation of an olefin using a carbene that is generated by the decomposition of a diazo compound in the presence of a catalytic amount of a transition- metal complex, is a powerful strategy for the synthesis of [n. 1.0] bicyclic ring systems.[1] In recent years, the transition-metal-catalyzed cycloisomerization of enynes has emerged as a useful complementary alternative method that avoids the use of the potentially hazardous ...
