A base-controlled chemo-selective reaction of vinylanilines with alkyl/aryl isothiocyanates to afford quinoline-2-thione and 2-aminoquinoline derivatives, is reported/. Quinoline-2-thiones I (R = Me, MeO, Cl, etc.; Ar = Ph, 4-MeOC6H4, 4-MeC6H4, 4-ClC6H4, etc.) could be obtained in high yields in the presence of Et3N. Particularly interesting is that the reaction could produce the 2-aminoquinolines II (R1 = Me, MeO, Cl, etc.; R2 = Ph, 3-MeC6H4, 4-FC6H4, 4-pentylC6H4; R3 = Ph, 4-MeC6H4, 4-FC6H4, etc.) in the presence of K3PO4 with high selectivity. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Formula: C4H7NS).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Formula: C4H7NS
