Abstract

AbstractThe transannular cyclization of epoxycaryophyllenes 2–7 catalyzed by TiIII has been investigated. This cyclization led to alcohols 8–15, all of them possessing a tricyclo[6.3.0.02,5]undecane skeleton. All of these compounds present pleasant aromatic properties. The cyclization takes place with high yields (> 80 %) and via the αα or ββ conformation of the intermediate radical I. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
