The reaction of linear push–pull enamines bearing a methyl group at the α-position with a set of trifluoromethylated carbonyl compounds was investigated. It has been found that the reaction proceeds at the methyl group of the enamines. The first computational study of the reaction between push–pull enamines and strong electrophilic reagents was reported. Out of three pathways considered DFT and MP2

The reaction of ‘push-pull’ enamines having a methyl group at the α-position with methyl 3,3,3-trifluoropyruvate was investigated. As a result, unexpected addition of pyruvate to methyl group was found and a set of polyfunctionalized β-dicarbonyl compounds was obtained. Possible mechanism of the reaction is discussed.

A metal-free regioselective γ-C(sp3)–H sulfenylation of enaminones with heterocyclic thiols is reported. This transformation is efficient, mild, scalable, and environmentally friendly and tolerates a large variety of enaminones substrates and heterocyclic thiols. The utility of this strategy is demonstrated in a late-stage modification of bioactive natural products and drug derivatives.
