The direct employment of benzylic and allylic alcohols as N-alkylating agents provides a useful synthetic route for amine derivatives by avoiding the preactivation of the hydroxygroups of alcohols. Herein we report a novel by-product-catalyzed three-component synthesis of amine derivatives from readily available benzylic and allylic alcohols, acyl chlorides (chloroformates or sulfonyl chlorides),

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.
