A novel synthesis of the title compound has been accomplished starting with alcohol (3) which in turn was prepared from the Wieland-Miescher ketone (1). Alcohol (3) was converted in six steps to ketoester (8) which after reduction, mesylation, and demesylation afforded the unsaturated ester (9). Its conversion to the desired compound (11) was achieved debenzylation followed by oxidation and Wittig reaction.
