The well-established Nenitzescu reaction of imines of beta-dicarbonyl systems, as their enamine tautomers, with benzoquinone has been applied to a wide range of such imines to give 5-hydroxyindoles, some of which are of significant biological importance. This reaction has now been extended to the benzylimines of simple ketones, including those of the potent mu-opioid receptor antagonists naltrexone
