  Highly Enantioselective Synthesis of Dihydroquinazolinones Catalyzed by SPINOL-Phosphoric Acids

  摘要：

  The asymmetric condensation/amine addition cascade sequence of 2-aminobenzamides and aldehydes catalyzed by chiral spirocyclic SPINOL-phosphoric acids was realized. SPINOL-phosphoric acid 1j was found to be a general, highly enantioselective organocatalyst for such cascade reactions at room temperature, affording 2,3-dihydroquinazolinones in excellent yields (up to 99%) with good to excellent ee's (up to 98%). The best level of stereocontrol was obtained for aromatic aldehydes with an ortho substituent.

  2-aminobenzamide and aldehydes, catalyzed by a novel chiral organocatalyst, was realized. The organocatalyst was found to be very effective and highly enantioselective for such cascade reactions at room temperature, affording 2,3-dihydroquinazolinones in excellent yields (up to 99%) with enantiomeric excesses of up to 97%. The best level of stereocontrol was obtained for aromatic/aliphatic aldehydes with ortho
