Zou, Y., & Millar, J.G. 2009 Synthesis of the pheromone of the longtailed mealybug, a sterically congested, irregular monoterpenoid.. Journal of Organic Chemistry 74(18): 7207-7209
Notes: (Chemical Equation Presented) A straightforward and scaleable synthesis of the sterically congested pheromone of the longtailed mealybug, with two adjacent quarternary carbons in a cyclopentene ring, was accomplished in 13.5% overall yield. Key steps included regiospecific cyclization of an ?-diazo-?- ketoester to build the cyclopentane ring, followed by reduction of the enol triflate of the ketone to place the double bond.
