  Ynones are privileged building blocks in various organic syntheses of heterocyclic derivatives due to their multifunctional nature, and flavones are an important class of natural products with a wide range of biological activities. We describe the catalytic double decarboxylative alkynylation of arylpropiolic acids with α‐keto acids. With Ag(I)/persulfate as the catalysis system, the valuable ynones

  In an effort to identify novel anti-inflammatory compounds, a series of flavone derivatives were synthesized and biologically evaluated for their inhibitory effects on the production of nitric oxide (NO) and prostaglandin E2 (PGE2), representative pro-inflammatory mediators, in LPS-induced RAW 264.7 cells. Their structure-activity relationship was also investigated. In particular, we found that compound

  A domino reaction between 2‐hydroxy‐/2‐aminobenzaldehydes and α‐haloketones gives chromen‐4‐ones and quinolin‐4‐ones in good to excellent yields. This method represents a new extension of the Allan–Robinson and Friedländer reactions, and uses N‐heterocyclic‐carbene catalysis. This approach has the advantages of operational simplicity, ambient reaction conditions, and no by‐product formation.
