Preparation of tertiary amines via the oxidative coupling of polyfunctional aryl and heteroaryl amidocuprates

Kienle, Marcel,Dubbaka, Srinivas Reddy,Del Amo, Vicente,Knochel, Paul

, p. 1272 - 1278 (2007)

Highly functionalized tertiary amines can be prepared by the oxidative coupling of polyfunctional lithium amidocuprates using chloranil as an oxidant. A high functional group tolerance and insensibility to steric hindrance characterize this general aminat
