Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1445085-77-7, is researched, SMILESS is O=S(O[Pd]C1=CC=CC=C1C2=C(C=CC=C2)N)(C)=O.CC(C)OC3=CC=CC(OC(C)C)=C3C4=CC=CC=C4P(C5CCCCC5)C6CCCCC6, Molecular C43H56NO5PPdSJournal, Article, Research Support, Non-U.S. Gov’t, Journal of Organic Chemistry called Palladium-Catalyzed C-4 Selective Coupling of 2,4-Dichloropyridines and Synthesis of Pyridine-Based Dyes for Live-Cell Imaging, Author is Yang, Min; Chen, Jing; He, Chen; Hu, Xin; Ding, Yechun; Kuang, Ying; Liu, Jinbiao; Huang, Qitong, the main research direction is palladium catalyst coupling dichloropyridine boronic ester toxicity cell imaging; pyridine dye palladium catalyst coupling dichloropyridine boronic ester.Reference of Methanesulfonato(2-dicyclohexylphosphino-2′,6′-di-i-propoxy-1,1′-biphenyl)(2′-amino-1,1′-biphenyl-2-yl)palladium(II).
An alternative process of Pd-catalyzed C-4 selective coupling of 2,4-dichloropyridines with boronic esters was developed, which afforded 24 examples of C-4 coupled pyridines in moderate to good yields. After further arylation, 21 examples of C-2, C-4 diarylated pyridines with a significant photophys. property were obtained, which were applied as pyridine-based dyes into live-cell imaging with good biocompatibility and low toxicity.
