摘要
(Chemical Equation Presented) The rapid and stereoselective construction of highly functionalized cyclopentenes is possible through gold(I)-catalyzed 5-endo hydroxy- and methoxycyclizations of 1,5-enynes. More complex 5,7-and 5,8-fused bicyclic structures of a type found in many terpene natural products can be formed by combining the cyclization reaction with ring-closing metathesis (RCM; see scheme). © 2007 Wiley-VCH Verlag GmbH & Co.
