A general, effective and convenient protocol for the direct synthesis of various 2-aminoquinolines I [R1 = H, 3-Me, 6-CH=CHPh, etc.; R2 = H, n-Bu, 2-pyridyl, etc.] through AgBF4-catalyzed amination of quinoline N-oxides with isothiocyanates under base-, oxidant-free and mild conditions was developed. A sequential one-pot amination/cyclization could be performed to convert the quinoline-N-oxide into benzo[4,5]imidazo[1,2-a]quinoline without isolating any reaction intermediates. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Reference of 2253-73-8).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Reference of 2253-73-8
