Sung, Dan-Bi; Mun, Bohyun; Park, Sol; Lee, Hyi-Seung; Lee, Jihoon; Lee, Yeon-Ju; Shin, Hee Jae; Lee, Jong Seok published the artcile< Synthesis, Molecular Engineering, and Photophysical Properties of Fluorescent Thieno[3,2-b]pyridine-5(4H)-ones>, Formula: C11H17BN2O2, the main research area is thienopyridinone synthesis regioselective aza cycloaddition aminothiophene unsaturated carboxylic acid; fluorescent thienopyridinone synthesis.
We describe a synthetic approach for a set of fluorescent thieno[3,2-b]pyridine-5(4H)-one derivatives and their photophys. properties. These fluorophores are prepared by a series of reactions employing the Suzuki-Miyaura cross-coupling reaction and a regioselective aza-[3 + 3] cycloaddition of 3-aminothiophenes with α,β-unsaturated carboxylic acids. Our findings revealed that the photophys. properties are chem. tunable by an appropriate choice of functional group on the thieno[3,2-b]pyridine-5(4H)-one scaffold.
Journal of Organic Chemistry published new progress about [3+3] Cycloaddition reaction (regioselective aza-[3 + 3] cycloaddition). 229009-40-9 belongs to class piperazines, and the molecular formula is C11H17BN2O2, Formula: C11H17BN2O2.
