Electrochemical C–H Alkylation of Azauracils Using N-(Acyloxy)phthalimides

Organic Letters, Год журнала: 2024, Номер 26(34), С. 7227 - 7232

Опубликована: Авг. 20, 2024

We present an electrochemical alkylation of azauracils using N-(acyloxy)phthalimides (NHPI esters) as readily available alkyl radical progenitors under metal- and additive-free conditions. Several are shown to undergo with array NHPI esters (1°, 2°, 3°, sterically congested), providing the desired products in good excellent yields. This operationally simple method is robust, scalable, suitable for both batch flow setups.

Visible-Light-Induced C–H Alkylation of 1,2,4-Triazine-3,5(2H,4H)-diones via Infrequent 1,2-Hydrogen-Atom Transfer

The Journal of Organic Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Май 19, 2025

1,2,4-Triazine-3,5(2H,4H)-diones are widely present in various drug molecules and bioactive molecules. A visible-light-driven C-H alkylation of 1,2,4-triazine-3,5(2H,4H)-diones via 1,2-hydrogen-atom transfer (1,2-HAT) amide radicals is first reported, providing an environmentally friendly sustainable pathway to enrich the structural functional diversity 1,2,4-triazine-3,5(2H,4H)-diones. This novel protocol characterized by mild metal-free reaction conditions, operationally simple method, good group tolerance. To our delight, other heterocycles, such as isoquinoline coumarin, also undergo reactions construct C(sp2)-C(sp3) bonds infrequent 1,2-HAT under current conditions.

Photocatalyzed Acylation of Azauracil Derivatives with Aldehydes

The Journal of Organic Chemistry, Год журнала: 2024, Номер 89(15), С. 11083 - 11087

Опубликована: Июль 24, 2024

A novel approach for the acylation of azauracil derivatives with aldehydes has been developed utilizing sodium decatungstate (NaDT) as a photocatalyst. This method demonstrates broad substrate tolerance and yields moderate to excellent outcomes. Notably, it aligns green chemistry principles by eliminating oxidants, eco-friendly energy sources, offering high scalability operational simplicity.
