An efficient synthesis of substituted quinazolin-4(3H)-ones by a one-pot ligand-free CuI-catalyzed coupling/condensative cyclization under mild conditions is described. Our study provides an alternative strategy for the preparation of biologically active quinazolin-4(3H)-ones.
N-C axiallychiral compounds have emerged recently as appealing motifs for drug design. However, the enantioselectivesynthesis of such molecules is still poorly developed and surprisingly no metal-catalyzed atroposelective N-arylations have been described. Herein, we disclose an unprecedented Cu-catalyzed atroposelective N-C coupling that proceeds at room temperature. Such mild reaction conditions
