The movement of substrates through our proposed cascade depended upon a combination of factors, including temperature, strength of various oxygen metal bonds, phenol and alcohol acidity, migratory aptitude of phenol protecting groups, its inclination toward β-elimination, and the propensity for the o-QM intermediate to undergo the subsequent 1,4-conjugate addition.
