## Abstract A novel oneβpot approach for the synthesis of aryl substituted quinazolinβ4(3__H__)βones and 2,3βdihydroβ4(1__H__)βquinazolinones has been reported based on the reductive desulfurization of 3βarylβ2βthioxoβ4(3__H__)βquinazolinones with nickel boride in dry methanol at ambient temperatur
The structures of the title compounds C 26 H 37 N 2 O 2 Sn (I) and C 14 H 9 IN 2 O 2 (II) were determined by singlecrystal X-ray diffraction technique. Compound I crystallizes in the triclinic space group P1 with a = 9.560(3) Γ , b = 16.899(6) Γ , c = 17.872(5) Γ , Ξ± = 65.957(7)Β°, Ξ² = 83.603(5)Β°, Ξ³ο¨ =
