Competition between alkenes in intramolecular ketene-alkene [2 + 2] cycloaddition: What does it take to win?

(Chemical Equation Presented). In the course of developing a new synthetic methodology using ketenes in sequential cycloaddition steps, we were faced with a competition problem with molecules containing a ketene tethered to more than one reacting partner.
