Cinchona alkaloid-derived primary amines were used as organocatalysts for the preparation of enantioenriched coumarin derivatives. A series of optically active coumarin derivatives was obtained in good yields with excellent enantioselectivities (up to 98%
Dual Role of Oxoaldehydes: Divergent Synthesis of 3-Aryl- and 3-Aroylcoumarins

, (2022/02/16)
A facile and efficient synthetic approach to various valuable 3-aryl- and 3-aroylcoumarins by the direct arylation and aroylation of coumarins with glyoxals in a metal-free manner is presented. The aryl glyoxal is for the first time recognized to serve as an aryl surrogate in addition to its role as an aroyl transfer reagent via a simple switch in reaction conditions. The approach accommodates a broad substrate scope and high yields of the two types of cross-coupling reactions starting from identical starting materials.
Palladium-Catalyzed Carbonylation of Coumarin C(sp 2)-H Bonds: A New Entry to Arylcoumarin Ketones

, p. 1680 - 1688 (2019/03/26)
A facile and efficient palladium-catalyzed carbonylation of coumarins involving two C-C bond formations has been developed. The C-H bond oxidative functionalization proceeds through aroylation with insertion of carbon monoxide to give arylcoumarin ketones
