Preview

A facile synthesis of β-amino-α,β-unsaturated carbonyl compounds has been accomplished by the reaction of (E)-N,N-dimethyl enaminones with isothiocyanates under metal, catalyst, base, and additive-free conditions. The reaction is straightforward, and offers transamination with good substrate scope and functional group tolerance. Notably, the aryl isothiocynates serve both as an amine surrogate as well as an activating agent.
