Title: Junjie Tian - Innovator in Pyridine Chemistry
Introduction
Junjie Tian is a notable inventor based in Tianjin, China. He has made significant contributions to the field of chemistry, particularly in the preparation of meta-functionalized pyridine compounds. His innovative methods have the potential to impact various applications in chemical synthesis.
Latest Patents
Junjie Tian holds a patent for a method for preparing a meta-functionalized pyridine compound. This method involves a two-step process. The first step includes the preparation of 1,4-dihydropyridine by adding a catalyst, a solvent, pinacolborane, and pyridine to a reaction flask in a nitrogen-filled glove box. The mixture is stirred at temperatures ranging from 40 to 110° C. for a duration of 5 to 12 hours. The second step involves the catalyzed functionalization of pyridine at the meta-position. This is achieved by adding an imine, an aldehyde, a ketone, or a halogenation reagent to the reaction flask. The mixture is stirred in a nitrogen atmosphere until the reaction is complete, followed by distillation under reduced pressure to remove the solvent and column chromatography separation to obtain the desired meta-functionalized pyridine. The reaction temperature remains between 40 to 110° C., with a reaction time of 5 to 24 hours.
