Visible-light-induced regioselective alkylation of coumarins via decarboxylative coupling with N-hydroxyphthalimide esters

, p. 2064 - 2068 (2019)
An efficient photocatalytic decarboxylative 3-position alkylation of coumarins by using alkyl N-hydroxyphthalimide esters as alkylation reagents has been developed. A variety of NHP esters derived from aliphatic carboxylic acids (primary, secondary, and tertiary) has been proved to be tolerated for this decarboxylation process, affording a broad scope of 3-alkylated coumarin derivatives in moderate to excellent yields. This protocol was highlighted by its mild conditions, readily available starting materials, operational simplicity, and wide functional group tolerance.

With sunlight or blue LEDs irradiation, regioselective decarboxylative alkylation of various non-aromatic heterocycles has been realized via C(sp3)-centered radical C(sp2)?C(sp3) bond formation under oxidant-free condition
Catalyst-free Decarboxylation and Decarboxylative Giese Additions of Alkyl Carboxylates through Photoactivation of Electron Donor-Acceptor Complex

, p. 4500 - 4505 (2019)
We report herein a catalyst-free method to perform decarboxylative conjugated addition and hydrodecarboxylation of aliphatic N-(acyloxy)phthalimides (redox active esters, RAEs) through photoactivation of electron-donor-acceptor (EDA) complex with Hantzsch ester (HE) in N,N-dimethylacetamide (DMA) solution. The reactions present a green method to decarboxylatively construct carbon-carbon bond and to perform hydrodecarboxylation with broad substrate scope and functional group tolerance under mild blue light irradiation condition without recourse of popularly used photoredox catalysts. (Figure presented.).
