Application of 2879-20-1, New Advances in Chemical Research, May 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In a document type is Article, and a compound is mentioned, 2879-20-1, Name is 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone, introducing its new discovery.
A new one-pot palladium-catalyzed process between N-tosylhydrazones, N-(dihalophenyl)-imidates, and amines was designed. This reaction involves Barluenga cross-coupling and N-arylation followed by cyclization to produce functionalized benzimidazoles. During this transformation, one C=C bond and two C=N bonds were created by a single palladium-catalyzed reaction. Depending on the starting materials, a library of 5-(1-arylvinyl)-1H-benzimidazoles was synthesized. Among several arylvinylbenzimidazole derivatives evaluated, one compound exhibits excellent antiproliferative activity in the nanomolar concentration range against human colon carcinoma cell lines (HCT-116) and human lung adenocarcinoma epithelial cell lines (A549).
