Direct Synthesis of Dialkyl Ketones from Deoxygenative Cross-Coupling of Carboxylic Acids and Alcohols

Chemical Science, Journal Year: 2024, Volume and Issue: unknown

Published: Jan. 1, 2024

Carboxylic acids and alcohols are widely commercially available, structurally diverse, benchtop stable, ubiquitous in both natural products pharmaceutical agents, making them ideal coupling partners for organic synthesis. Though various transformations have been developed by enabling the activation subsequent cross-coupling of carboxylic separate contexts, direct these two structural motifs to build value-added molecules is rare. Herein, we a deoxygenative between dialkyl ketone synthesis

Organometallic Photocatalyst‐Promoted Synthesis and Modification of Carbohydrates under Photoirradiation

The Chemical Record, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 27, 2024

Carbohydrates are natural, renewable, chemical compounds that play crucial roles in biological systems. Thus, efficient and stereoselective glycosylation is an urgent task for the preparation of pure structurally well-defined carbohydrates. Photoredox catalysis has emerged as a powerful tool carbohydrate chemistry, providing alternative addressing some challenges glycochemistry. Over last few decades, Ir- Ru-based organometallic photocatalysts have attracted significant interest because their high stability, high-energy triplet state, strong visible-light absorption, long luminescence lifetime, amenability to ligand modification. This review highlights recent progress photocatalyst-promoted synthesis modification carbohydrates under photoirradiation, well related benefits drawbacks.
