Aboonajmi, Jasem; Panahi, Farhad; Sharghi, Hashem published their research in ACS Omega in 2021. The article was titled 《One-Pot Multicomponent Coupling Reaction of Catechols, Benzyl Alcohols/Benzyl Methyl Ethers, and Ammonium Acetate toward Synthesis of Benzoxazoles》.Reference of 2-(2-Hydroxyethyl)pyridine The article contains the following contents:
The multicomponent coupling reaction of catechol, ammonium acetate, and benzyl alc./benzyl Me ether in the presence of a Fe(III) catalyst precursor afforded benzoxazole derivatives in good to excellent yields. The notable features of this protocol are abundant availability of the catalyst system, large-scale synthesis, high diversity, and high yields of products.2-(2-Hydroxyethyl)pyridine(cas: 103-74-2Reference of 2-(2-Hydroxyethyl)pyridine) was used in this study.
2-(2-Hydroxyethyl)pyridine(cas: 103-74-2) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.Reference of 2-(2-Hydroxyethyl)pyridine
