N-Aryl-α-ketoenamine 2a reacts with methyl-p-benzoquinone 1a to yield the hydroquinone adduct 3a.This is oxidized to the stable quinone 5a, which is cyclisized to indolequinone 4 and the quinonoid heterocyclus 6a.Compounds 6a and 4 are reduced and acetylated to hydroquinones 9a and 7, respectively.The path of the reaction is discussed.Reaction of 1b and 2b yields directly quinone 6b.
