Divergent Synthesis of Aziridine and Imidazolidine Frameworks under Blue LED Irradiation

Organic Letters, Год журнала: 2021, Номер 23(11), С. 4109 - 4114

Опубликована: Май 14, 2021

We develop a visible light-promoted divergent cycloaddition of α-diazo esters with hexahydro-1,3,5-triazines, leading to series aziridine and imidazolidine frameworks in average good yield, by simply changing the reaction media used. It is noteworthy that occurs under sole light irradiation without need for exogenous photoredox catalysts. More significantly, reasonable mechanism was proposed on basis control experiments density functional theory calculation results.

Abstract In the quest for sustainable processes, selection of resources and catalysts is central importance. Carboxylic acids, which are abundant, stable ideally biobased feedstocks, can be considered as attractive platforms towards a range functionalized molecules. A recent resurgence photoinduced ligand‐to‐metal charge transfer (LMCT) carboxylates led to tremendous developments in field earth‐abundant metal mediated, visible‐light induced (non)‐decarboxylative transformations carboxylic acids. These reactions combine use available starting materials, low‐consuming energy source abundant catalysts. Besides these undeniable advantages, they also provide mild, highly selective innovative conditions complex molecule functionalization. The objective this review give an overview advances LMCT with special focus on mechanistic aspects transformations. magnified image

Photoinduced Three-Component Difluoroalkylation of Quinoxalinones with Alkenes via Difluoroiodane(III) Reagents

Organic Letters, Год журнала: 2022, Номер 24(19), С. 3576 - 3581

Опубликована: Май 12, 2022

An environmentally friendly strategy for the photocatalyzed three-component reaction between quinoxalinones, alkenes, and hypervalent iodine(III) reagents is disclosed. The new designed difluoroiodane(III) reagent shows excellent reactivity, providing a wide range of difluoroalkyl-substituted quinoxaline-2(1H)-ones in moderate to yields under mild conditions. Experimental studies demonstrated that difluoroalkyl radical intermediate was involved this reaction.
