Abstract

A concise organocatalytic method for the facile synthesis of some novel 1′H-spiro[cycloalkyl-1,2′-quinazolin]-4′(3′H)-ones via a one-pot, three-component condensation of isatoic anhydride, aryl or aliphatic amines and a cyclic ketone is described.

  • 25 1 H-Spiro[cycloalkyl-1,2-quinazolin]-4(3 H)-ones 4a– l and 6al; General Procedure A 50 mL round-bottomed flask was charged with MeOH (5 mL), isatoic anhydride (2; 3 mmol), the appropriate amine 1 (3 mmol), and AcOH (10 mol%), and the mixture was stirred at r.t. for about 5 min. Cyclohexanone or cyclopentanone (3 mmol) in MeOH (5 mL) was added, and the resulting mixture was stirred at the reflux temperature until the reaction was complete [TLC; EtOAc–hexane (3:7); see Tables 2 and 3]. The mixture was allowed to cool to r.t., and the resulting solid was collected by filtration. The crude product was purified by crystallization from EtOH.

  • 27 Crystals of compounds 4a, 4e, and 6e were mounted on a Gemini A Ultra Oxford Diffraction automatic diffractometer equipped with a CCD detector. Data were collected with graphite-monochromated MoKα radiation (λ = 0.71073 Å) at 295(2) K with an ω scan mode. Lorentz, polarization, and empirical absorption corrections using spherical harmonics implemented in the SCALE3 ABSPACK scaling algorithm were applied.30 The structure was solved by direct methods and subsequently completed by difference Fourier recycling. Nonhydrogen atoms were refined anisotropically by using the full-matrix least-squares technique. Hydrogen atoms were found by difference Fourier synthesis after four cycles of anisotropic refinement, and refined as riding on the adjacent carbon atom with an individual isotropic temperature factor equal to 1.2 times the value of equivalent temperature factor of the parent atom. Olex231 and SHELXS, SHELXL32 programs were used for all the calculations.
