Thiyagarajan, Subramanian published the artcileKOtBu-Catalyzed Michael Addition Reactions Under Mild and Solvent-Free Conditions, HPLC of Formula: 517-23-7, the publication is Chemistry – An Asian Journal (2020), 15(4), 518-523, database is CAplus and MEDLINE.
Herein, a mild and environmentally friendly strategy of readily available KOtBu-catalyzed Michael addition reactions was demonstrated. This simple inorganic base efficiently catalyzed the Michael addition of underexplored acrylonitriles, esters and amides with oxa-, aza-, and thia-heteroatom nucleophiles to afford Michael addition products. This catalytic process proceeded under solvent-free conditions and at room temperature Notably, this protocol offered an easy operational procedure, broad substrate scope with excellent selectivity, reaction scalability and excellent TON (>9900). Preliminary mechanistic studies revealed that the reaction followed an ionic mechanism. Formal synthesis of promazine was demonstrated using this catalytic protocol.
