Oxidative Free-Radical C(sp²)–H Bond Chlorination of Enaminones with LiCl: Access to Highly Functionalized α-Chlorinated Enaminones

The Journal of Organic Chemistry, Год журнала: 2024, Номер 89(12), С. 8521 - 8530

Опубликована: Июнь 3, 2024

An oxidative free-radical C(sp2)–H bond chlorination strategy of enaminones has been developed by using LiCl as a chlorinating reagent and K2S2O8 an oxidant. This transformation provides new straightforward synthetic methodology to afford highly functionalized α-chlorinated with Z-configuration in good excellent yields.

Three-Component Reaction for the Synthesis of Spiro-Heterocycles from Isatins, Substituted Ureas, and Cyclic Ketones

The Journal of Organic Chemistry, Год журнала: 2024, Номер 89(5), С. 3441 - 3452

Опубликована: Фев. 20, 2024

We reported an efficient three-component reaction to access new spiro heterocycles through the annulation reactions of isatins, substituted ureas, and cyclic ketones under normal laboratory conditions, which is another example isatins being used build compounds by ring-opening recyclization processes. The wide range substrates, simple operation, experimental high yields make approach practical value.

Annulation Cascades of Cyclosulfonium Salts and Alkenes towards Sulfur‐Containing N‐Heterocycles by Visible Light/Copper Catalysis

Chinese Journal of Chemistry, Год журнала: 2024, Номер 42(14), С. 1637 - 1643

Опубликована: Апрель 3, 2024

Comprehensive Summary Although, great achievements have been made in the synthesis of heterocycles using radical addition/cyclization strategy, developing versatile alkyl precursors, especially non‐stabilized long chain radicals for this strategy still remains a huge challenge. Herein, we report an efficient annulation cascade reaction between cyclosulfonium salts and alkenes sulfur‐containing N ‐heterocycles by visible light/copper catalysis under mild conditions. The C—S bond cleavage/radical delivers variety corresponding containing aryl thioether motifs with good functional group tolerance. Significantly, current system could be used late‐stage functionalization complex bioactive molecules.
