I found the field of Chemistry very interesting. Saw the article New Multicomponent Synthesis of Functionalized Nitriles and Esters of 6-Alkylsulfanyl-1,4-dihydronicotinic Acids published in 2020.0. Recommanded Product: 3-Pyridinecarboxaldehyde, Reprint Addresses Dyachenko, VD (corresponding author), T Shevchenko Lugansk Natl Univ, UA-91011 Lugansk, Ukraine.. The CAS is 500-22-1. Through research, I have a further understanding and discovery of 3-Pyridinecarboxaldehyde
The multicomponent condensation of malononitrile, hydrogen sulfide, aryl or hetaryl aldehydes, 1,3-dicarbonyl compounds and alkylating reagents afforded functionalized nitriles and esters of 6-alkylsulfanyl-1,4-dihydronicotinic acids, their aromatic analogues and 1,4-dihydrothieno[2,3-b]pyridines.
Recommanded Product: 3-Pyridinecarboxaldehyde. About 3-Pyridinecarboxaldehyde, If you have any questions, you can contact Kalashnik, IN; Dyachenko, VD or concate me.
