The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Methyl 2,4-dichloronicotinate( cas:442903-28-8 ) is researched.Related Products of 442903-28-8.Yang, Min; Chen, Jing; He, Chen; Hu, Xin; Ding, Yechun; Kuang, Ying; Liu, Jinbiao; Huang, Qitong published the article 《Palladium-Catalyzed C-4 Selective Coupling of 2,4-Dichloropyridines and Synthesis of Pyridine-Based Dyes for Live-Cell Imaging》 about this compound( cas:442903-28-8 ) in Journal of Organic Chemistry. Keywords: palladium catalyst coupling dichloropyridine boronic ester toxicity cell imaging; pyridine dye palladium catalyst coupling dichloropyridine boronic ester. Let’s learn more about this compound (cas:442903-28-8).
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.
After consulting a lot of data, we found that this compound(442903-28-8)Related Products of 442903-28-8 can be used in many types of reactions. And in most cases, this compound has more advantages.
