Photooxygenation of masked o-benzoquinones: An efficient entry into highly functionalized cyclopentenones from 2-methoxyphenols

(Chemical Equation Presented) MOB tactics: A novel oxidation of masked o-benzoquinones (MOBs) 1 occurs by singlet-oxygen-triggered ring contraction to form cyclopentenone derivatives 2 and by [4+2] cycloaddition to give endoperoxides 3. The competing path

New oxygen-activating systems for dehydrogenation of 2-hydroxymethyl phenols 1 (a: R = tBu ; b: R = CH3; c : R = H) to the corresponding salicylaldehydes 3 are described. These systems are composed of a transition metal (M0 = Fe0 or Cu0), a transition metal ion (MnCln=Fe11Cl2 or Cu1Cl) in catalytic amount and molecular oxygen. The most active systems are Fe0FeCl2O2CH3OH and Cu0CuCl + FeCl2O2CH3OH. Based on all the results so far obtained a mechanistic hypothesis is proposed.
