5-Cyclodecenones were made by RCM, using the first generation Grubbs catalyst and infinite dilution in refluxing dichloromethane. A convenient one-pot procedure for making 2,6-disubstituted cyclohexanones was developed, which allowed for the synthesis of a bridged bicyclo compound, containing a 5-cyclodecenone. Transannular cyclization of this substrate led to a tricyclic product. The overall three-pot sequence of dialkylation, RCM, and transannular cyclization results in bisannulation on a pre-existing ring. (C) 2016 Elsevier Ltd. All rights reserved.
