COA of Formula: C7H6BrNO2. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Methyl 6-bromonicotinate, is researched, Molecular C7H6BrNO2, CAS is 26218-78-0, about Enantioselective Synthesis of Dihydropyridines Containing Quaternary Stereocenters Through Dearomatization of Pyridinium Salts.
Enantioselective synthesis of non-aromatic heterocycles containing a quaternary stereogenic center is a challenging synthetic problem. A strategy towards this problem involving dearomatization of N-alkylpyridinium salts using boronic acid nucleophiles have been described. This dearomatization reaction is catalyzed by Rhodium(I)/BINAP catalyst and delivers dihydropyridines that contain a fully substituted stereogenic center alpha to the ring nitrogen atom in high yield and enantioselectivity. The reaction is compatible with a wide range of functional groups such as halide, ester, amide, olefin and free alc. Derivatization of dehydropyridine products allows synthesis of the functionalized tetrahydropyridines and piperidines.
