Computed Properties of C7H9NO2In 2018 ,《””Reverse”” pyridyl cryptands as hosts for viologens》 appeared in Heteroatom Chemistry. The author of the article were Pederson, Adam M.-P.; Price, Terry L. Jr; Schoonover, Daniel V.; Slebodnick, Carla; Gibson, Harry W.. The article conveys some information:
Two new cryptands were prepared from bis(m-phenylene)-32-crown-10 (BMP32) 5,5′-diacid chloride and dibenzo-30-crown-10 (DB30) 4,4′-diacid chloride, resp., by reaction with pyridine-2,6-dimethanol. The resultant cryptands have the ester moieties reversed from previously reported isomers. These “”reverse”” cryptands display lower association constants with viologen derivatives than the original cryptands; this is rationalized by the conjugation of the ester moieties with the aromatic rings, which reduces their electron-donating properties and offsets the increased basicity of the pyridyl nitrogen atoms. The crystal structure of the BMP32-based cryptand indeed confirms the coplanarity of the ester and aromatic moieties and indicates that, as a result, the available cavity is quite small and that the pyridyl nitrogen atom points away from the cavity. After reading the article, we found that the author used 2,6-Pyridinedimethanol(cas: 1195-59-1Computed Properties of C7H9NO2)
2,6-Pyridinedimethanol(cas: 1195-59-1) belongs to pyridine. Pyridine and pyridine-derived structures are privileged pharmacophores in medicinal chemistry and an essential functionality for organic chemists. As the prototypical π-deficient heterocycle, pyridine illustrates distinctive chemistry as both substrate and reagent. Computed Properties of C7H9NO2
