A palladium-catalyzed arylation of N-acyl-N,O-acetals with arylboronic reagents: synthesis of diarylmethylamines protected by easily removable acyl group
摘要:
An efficient process was developed to synthesis diarylmethylamines protected by a readily removable acyl group using a palladium-catalyzed arylation of N-acyl-N,O-acetals with arylboronic reagents. The attractive features of this protocol are: the ease of preparing substrate and the mild reaction condition under an air atmosphere. Moderate enantioselectivity was observed in preliminary screening studies of chiral ligands. (C) 2015 Elsevier Ltd. All rights reserved.
