Continuous-flow hydration–condensation reaction: Synthesis of α,β-unsaturated ketones from alkynes and aldehydes by using a heterogeneous solid acid catalyst
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 heterogeneouscatalyst in a flow microwave. The procedure presents a straightforward and convenient access to valuable differently substituted chalcones and can be applied on multigram scale.

Synthesis and Evaluation of Chalcone and its Derivatives as Potential Anticholinergic Agents
intention for the analysis of such compounds. This study involved the synthesis of chalcones and their pyrazoline derivatives and their screening as cholinesterase inhibitors. The newly synthesized compounds were also investigated for their antioxidant potential. Methods: Chalcones were synthesized by well-established methods of synthesis and their structural elucidation was carried out by H-NMR, 13C-NMR
