Luo, Lihua;Tang, Juan;Sun, Rui;Li, Wenjing;Zheng, Xueli;Yuan, Maoling;Li, Ruixiang;Chen, Hua;Fu, Haiyan published 《Direct C-H Sulfonylimination of Pyridinium Salts》 in 2022. The article was appeared in 《Organic Letters》. They have made some progress in their research.Name: 3-Cyanopyridine The article mentions the following:
A direct pyridinium C-H sulfonylimination has been developed for the synthesis of sulfonyl iminopyridine derivatives I (R = H, CN, Ph, thiophen-2-yl, etc.; R1 = H, OMe, Ph, thiophen-3-yl, etc.; R2 = H, cyclopropyl, Ph, 4-bromophenyl, etc.; R1R2 = -CH=CH-CH=CH-; R3 = Me, Et, i-Pr, etc.; R4 = Et, Ph, pyridin-3-yl, etc.) with high efficiency. This transformation features the direct and efficient formation of a C=N bond with a high functional group tolerance under metal-free conditions. The spectroscopic properties potentially enable these sulfonyl iminopyridine compounds I to be useful new emitting materials. The experimental procedure involved many compounds, such as 3-Cyanopyridine (cas: 100-54-9) .
3-Cyanopyridine(cas: 100-54-9) also shows biological activity against autoimmune diseases, such as murine hepatitis, by inhibiting the proliferation of B cells and T cells.Name: 3-Cyanopyridine This drug is not effective against cancer cells because it does not inhibit DNA synthesis or protein synthesis.
