C3-Cyanation of Pyridines: Constraints on Electrophiles and Determinants of Regioselectivity.
Zhang M, Zhou Q, Luo H, Tang ZL, Xu X, Wang XC. Zhang M, et al. Angew Chem Int Ed Engl. 2023 Feb 1;62(6):e202216894. doi: 10.1002/anie.202216894. Epub 2023 Jan 9. Angew Chem Int Ed Engl. 2023. PMID: 36517651
Here, we report a method for C3-selective cyanation of pyridines by a tandem process with the reaction of an in situ generated dihydropyridine with a cyano electrophile as the key step. The method is suitable for late-stage functionalization of pyridine drugs. ...
