A one pot synthesis of the 3,3-dimethylacroyl enol ester function found in the vibsane type diterpenes has been developed based on the Anders-Gassner variant of the Wittig reaction (AGW reaction). This method uses easily accessible acyloxyalkylidene phosphoranes and a variety of aldehydes. (c) 2008 Elsevier Ltd. All rights reserved.
