C-alkylation of N-alkylamides with styrenes is reported, proceeding in ambient air/moisture to give arylbutanamides and pharmaceutically-relevant scaffolds in excellent mass balance. Various amide and styrene derivatives were tolerated, rapidly affording molecular complexity in a single step; thus highlighting the future utility of this transformation in the synthetic chemistry toolbox. Reaction scalability (up to 65 g/h product) was demonstrated using a Microwave Flow reactor, as the first example of a C-alkylation reaction using styrenes in continuous flow.
