Tandem Acylation and Aromatization of Vinylogous Esters: A Regiospecific Approach to Resorcinyl Ketones.

This study demonstrates the direct conversion of vinylogous esters into selectively protected 6-acyl resorcinols (4-alkoxy/aryloxy-2-hydroxy arylketones) in a regiospecific manner. Resorcinyl ketones are first-time synthesized, diverging from their traditional roots, originating from non-benzenoid pool materials. Converting cyclohexenones into phenol- or resorcinol-based arylketones remains challenging due to the stability and reactivity issues of intermediate products.

"TB drug stock planning in advance is a futile activity" health system's perceived challenges and suggested solutions pertaining to Nikshay Aushadhi portal in central India.
