标题:A Novel Highly Stereoselective Synthesis Of 2,3-Disubstituted 3H-Quinazoline-4-One Derivatives
摘要:An Efficient Three-Step Synthesis Of Chiral 3H-Quinazoline-4-One Derivatives From Commercial Materials Is Disclosed. The Mumm Reaction Of Imidoyl Chloride With Alpha-Amino Acids Followed By Reductive Cyclization Affords Enantiomerically Pure (Ee > 93%) Quinazoline-4-Ones In Good Overall Yield. A Comparison With Existing Approaches Indicates That This Method Is Superior For Hindered Substrates.
