A novel methodol. was developed for the synthesis of 3-substituted 2-thioxo-2,3-dihydroquinazolin-4(1H)-one derivatives I [R = i-Pr, Ph, Bn, etc.] based on the multicomponent one-pot reaction of Me 2-bromobenzoate, phenylisothiocyanate derivatives and sodium azide in the presence of copper bromide and L-proline under basic conditions. To show the generality of the method, various phenylisothiocyanates bearing electron-donating or electron-withdrawing functionalities were used and desired products were obtained in high isolated yields. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Formula: C4H7NS).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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
