A Mannich-type three-component reaction involving aldehydes, acetamide, and enolizable ketones or β-keto esters for the preparation of β-acetamido carbonyl compounds in the presence of TMSCl is described. This newly developed protocol is operationally convenient, widely applicable, and highly diastereoselective.

A series of novel curcuminoids were synthesised for the first time via a Mannich‐3CR/organocatalysed Claisen–Schmidt condensation sequence. Structure–activity relationship (SAR) studies were performed by applying viability assays and holographic microscopic imaging to these curcumin analogues for anti‐proliferative activity against A549 and H1975 lung adenocarcinoma cells. The TNFα‐induced NF‐κB inhibition
