Ethyl 5-keto-6-heptenoate, obtained by the action of vinyl magnesium bromide on ethyl 4-formyl butanoate and oxidation of the resulting alcohol with Jones' reagent, was submitted to the Wittig reaction with methylenetriphenylphosphorane to afford ethyl 5- methylene-6-heptenoate. Gignard reaction with :methyl magnesium iodide on the diene -ester furnished myrcenol.
