Research Progress in Organic Reactions Involving 4-Acyl/Carbamoyl/Alkoxycarbonyl Substituted Hantzsch Esters

Acta Chimica Sinica, Год журнала: 2023, Номер 81(6), С. 657 - 657

Опубликована: Янв. 1, 2023

In recent years, 4-acyl/carbamoyl/alkoxycarbonyl-substituted Hantzsch esters have been increasingly utilized as a new class of radical precursor reagents, emerging one major research topics for synthetic chemists.These compounds can generate the corresponding acyl, carbamoyl, and alkoxycarbonyl radicals under mild conditions through photochemical, electrochemical, or chemical oxidation systems, leading to wide array addition/coupling reactions.Due reducibility their dihydropyridine skeleton, these precursors often exhibit unique reactivities display good compatibility with transition metal-catalysis organocatalysis systems.In addition, reported reaction typically feature environmental friendliness, highly functional group-tolerance, biocompatibility, which should significant value in fields medicinal chemistry biology.Herein, this review summarizes progress carbamoyl radicals, focuses on generation system, mechanistic underpinnings, well uniqueness applications strategies such esters.
