An aryl thiol–vinyl azide coupling reaction and a thiol–vinyl azide coupling/cyclization cascade: efficient synthesis of β-ketosulfides and arene-fused 5-methylene-2-pyrrolidinone derivatives
The addition reaction of thiol to vinyl azide has been extensively studied. Variously substituted aryl thiols are all viable for this coupling process. The scope of the other partner is successfully expanded from α-aryl vinyl azide to α-alkyl vinyl azide. A thiol–vinyl azide coupling/cyclization cascade is realized with substituted aryl vinyl azides carrying a 2-methoxycarbonyl group. The value of

We describe herein parallel synthetic routes to isoindolo[2,1-a]indoles and 5H-indolo[2,1-a]isoquinolines from 2-(2-aminophenylethynyl)benzoicacid esters and [2-(2-aminophenyl-ethynyl)phenyl]aceticacid esters, respectively.

The targeting of polynucleotide (RNA and DNA) topologies and their protein complexes by small molecules has enormous potential in the discovery of new therapeutics across a broad range of diseases (infectious, chronic and congenital). Polynucleotides are very differentstructures to proteins and have a much greater capacity to form strong π,π-interactions with suitably π-rich small molecules. To exploit
