Multifunctionalization of Unactivated Cyclic Ketones via an Electrochemical Process: Access to Cyclic α-Enaminones

The multifunctionalization of unactivated cyclic ketones was developed via an electrochemically intermolecular α-amination under metal-free conditions. The reaction can be carried out smoothly with a broad scope of the aromatic amines substrates under mil

Reaction of 2-Amino-2-cyclopenten-1-one Derivatives with p-Benzoquinones, II

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.
