An Efficient Route for Synthesis of a New Class of Quinazolines: Synthesis of Thiazino-, Thiadiazolo-, and Thiazolo- Quinazoline Derivatives
The addition of amino group of anthranilic acid to isothiocyanate 2 provided cinnamoyl thiourea derivative 3. The compound 3 underwent different types of cyclization depending on conditions. The quinazolinthione of type 5 was obtained by treatment with Na2CO3. Quinazolinthione 5 underwent a series of transformation and oxidation reactions to form a new class of quinazoline and thiazoloquinazoline derivatives. All the compounds were tested against antimicrobial and antitumor activity.
Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 7689-03-4.
