Palladium-Catalyzed β-C-H Arylation of Aliphatic Aldehydes and Ketones Using Amino Amide as a Transient Directing Group.Org Lett. 2019 04 05; 21(7):2085-2089.OL
This paper describes a new amino-amide-based transient directing group (TDG). The TDG can exhibit better performance in the Pd-catalyzed arylation of aliphatic aldehydes and ketones. This reaction showed good substrate compatibility and regioselectivity. The results indicated that 3-amino- N-isopropylpropionamide was more beneficial to the β-arylation of aliphatic aldehydes than other TDGs under relatively mild conditions.
