A simple, practical and efficient continuous-flow hydration-condensation protocol was developed for the synthesis of alpha,beta-unsaturated ketones starting from alkynes and aldehydes by employing a heterogeneous catalyst in a flow microwave. The procedure presents a straightforward and convenient access to valuable differently substituted chalcones and can be applied on multigram scale.
