摘要：

(Chemical Equation Presented) Caught in a trap: Intermolecular cyclopropanation reactions of enynes with alkenes allows the synthesis of complex cyclic systems with gold(I) catalysts under mild conditions. Furthermore, gold carbenes are trapped intermolecularly with alkenes (see scheme; L = ligand), thereby providing experimental evidence for the involvement of two different types of metal carbenes in the skeletal rearrangement of enynes. © 2006 Wiley-VCH Verlag GmbH & Co.
