, p. 3154 - 3160 (2013)
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%

With the aim of finding new chemical entities selective for fish pathogens to avoid drug resistance in humans, a series of coumarin-chalcone hybrid compounds with different patterns of substitution were designed and synthesized. Their antibacterial activi
Dual Role of Oxoaldehydes: Divergent Synthesis of 3-Aryl- and 3-Aroylcoumarins
Ghandi, Mehdi,Jafarpour, Farnaz,Khodadadi, Meysam,Moazzam, Ali
, (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.
An efficient synthesis of some new coumarin hybrids endowed with expected biological activity

Reactions of 5-bromo-2-hydroxybenzaldehyde with cyanoacetic acid hydrazide derivatives in refluxing ethanol afforded some new chromene-based polyfunctionally substituted heteroaromatics. The antimicrobial activity of some of the obtained products was eval
Palladium-Catalyzed Carbonylation of Coumarin C(sp 2)-H Bonds: A New Entry to Arylcoumarin Ketones
Mirzaei, Siyavash,Rajai-Daryasarei, Saideh,Soheilizad, Mehdi,Kabiri, Roya,Ansari, Samira,Shabanian, Meisam,Pashazadeh, Rahim
, 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

Keshavarzipour, Fariba,Tavakol, Hossein
, p. 149 - 153 (2016/01/09)
In this work, choline chloride/zinc chloride was employed as a deep eutectic solvent (DES) in the green synthesis of coumarin derivatives using Knoevenagel condensation. Coumarins are important organic structures with useful application in various fields.
The indium(iii) chloride catalyzed synthesis of sulfur incorporated 3-acylcoumarins; Their photochromic and acetate sensing properties
Surya Prakash Rao,Desai, Avinash
, p. 63642 - 63649 (2015/02/19)
The synthesis and evaluation of the photochromic properties of 3-acylcoumarins are very important as they exhibit selective sensing properties. We found that InCl3 efficiently catalyzes the condensation of 2-hydroxybenzaldehydes and β-keto este
