An efficient, regiospecific, convergent route to o-al kylated phenols and thence to quinone monoacetals involves reaction of the corresponding 2-hydroxy carbonyl derivative with alkyl-lithium reagents, followed by triethylsilane reduction and electrochemical oxidation. ... Quinone monoacetals are established as valuable regiospecific quinone equivalents1 in organic synthesis, serving as pre- cursors to lignins,2 various polycyclic quinone natural prod- ucts,3 indoles,4 and ...
