Abstract
:
Coumarin is a privileged scaffold that contains the unique 2H-chromen-2-one motif, and its
derivatives are widely distributed in nature, especially in plants. In recent years, due to their diverse
pharmacological activities and remarkable photochemical properties, they have attracted significant
attention from scientists, which has also prompted the research on the synthesis approaches and the
availability of substrates for these compounds. This article is a brief description of the methods for the
synthesis of various coumarin derivatives via two- or multi-component reactions involving 3-amino
or 4-aminocoumarin reported during 2015-2021. This review may help expand the development of
various analogues with coumarin as the basic unit.

Abstract
An electrochemical method for synthesizing 1,2,4,5-tetrasubstituted imidazoles was developed under undivided electrolytic conditions. This synthesis was specifically realized based on electrochemical C(sp3)-H amination via enamines and amines. Readily available starting materials were used, avoiding the use of both transition metals and oxidants. The practicability of the method lies in its broad substrate adaptability and in its ability to provide a simple green pathway for synthesizing GABAA receptor analogs.

Abstract
A Friedländer-based method for transition-metal free, aerobic synthesis of chromene-fused quinolinones is reported. The coupling of 4-hydrocoumarins and 2-aminobenzyl alcohols proceeds in the presence of acetic acid solvent and oxygen oxidant, affording 6H-chromeno[4,3-b]quinolin-6-ones in good to excellent yields. The reactions are tolerant of functionalities such as alkyl, methoxy, bromo, chloro, and N-heterocycle. Isosteric cyclic 1,3-diketones and 2-amino acetophenones also give fused quinolinones under reaction conditions. The method herein offers a rapid and benign synthesis of hitherto challenging N-heterocycles. To our best knowledge, such a convenient pathway to obtain chromene-fused quinolinones have not been known in the literature. A Friedländer-based method for transition-metal free, aerobic synthesis of chromene-fused quinolinones is reported.![]()

Abstract
The one-pot protocol by the dendritic copper powder-mediated Knoevenagel condensation/annelation is delineated here for the synthesis of 3-amido-2-quinolones. It is practical with moisture tolerance and easy setup, and is compatible with many functional groups under mild conditions. This method was applied for the preparation of the key intermediates of biologically relevant 3-amido-2-quinolones.

Abstract
A copper catalyzed intramolecular 1,2-carboboration of o-aldiminyl cinnamate has been realized in both regio- and stereoselective fashions. This reaction provides a convenient entry to highly valuable and otherwise challenging cis-2,3,4-trisubstituted tetrahydroquinolines carrying a 4-boryl group. An unusual non-Michael addition intermediate or alternatively, a cyclic enolate is proposed to account for the intriguing all-cis configuration in the final products.
