Paragraph 0059-0060; 0063-0064, (2021/03/13)
Provided is a method for amidating a hydroxy ester compound at a high chemical selectivity. The amidation reaction method for a hydroxy ester compound comprises, in the presence of a catalyst containing a compound of a transition metal of the group 4 or group 5 in the periodic table, reacting at least one kind of hydroxy ester compound selected from the group consisting of an α-hydroxy ester compound, a β-hydroxy ester compound, a γ-hydroxy ester compound and a δ-hydroxy ester compound with an amino compound so as to amidate an ester group having a hydroxyl group at the α-, β-, γ- or δ-position of the hydroxy ester compound.

An unexpected reaction of cinnamylanilines was achieved through the radical cation salt-induced aerobic oxidation of sp3 C-H bonds, providing a series of 2-arylquinolines. The mechanistic study shows that the cinnamylaniline was oxidized to an imine, which was attacked by the aniline generated through decomposition of the corresponding imine. After further intramolecular cyclization and aromatization, 2-arylquinolines were obtained. This reaction provides a new method to construct 2-arylquinolines from readily accessible starting materials.
