Abstract
Formation of a nine-membered cyclic ether with E-configurated double bond was observed during construction of 5-9-5 tricycles through RCM of dienes. Ring fusion stereochemistry in the products oxonenes was found to have profound influence on the olefin geometry. cis-anti-cis 5-9-5 tricycle was obtained with Z-configurated olefin while cis-syn-cis 5-9-5 system was obtained with E- as well as Z-configurated double bond with the former predominating.
