Versatile Palladium-Catalyzed Approach to Acyl Fluorides and Carbonylations by Combining Visible Light- and Ligand-Driven Operations

We describe the development of a general palladium-catalyzed carbonylative method to synthesize acyl fluorides from aryl, heteroaryl, alkyl, and functionalized organic halides.

Enones from Acid Fluorides and Vinyl Triflates by Reductive Nickel Catalysis

, 2019
A nickel-catalyzed reductive coupling between acid fluorides and vinyl triflates has been described. This method provides an efficient access to various enones and avoids the requirement for acyl or vinyl metallic reagents in the conventional approaches.

Use of Acid Fluorides Increases the Scope of the Reductive Acylation of Esters

, 2016
The use of acyl fluorides in the Rychnovsky reductive acylation of esters allows a variety of esters to be converted to their corresponding α-acyloxy ethers in good to excellent yields, without the need to sacrifice an extra equiv of carboxylic acid ...

Suzuki-Miyaura cross-couplings from carboxylic acids via in situ acyl fluoride electrophiles

Acyl fluorides have been previously shown to be competent electrophiles in the generation of ketones via Suzuki-Miyaura Cross-Couplings. However, such methodologies rely on isolated, pre-formed acyl fluorides which hampers the scope and flexibility of ...

N-Heterocyclic Carbene-Catalyzed (4 + 2) Cycloaddition/Decarboxylation of Silyl Dienol Ethers with α,β-Unsaturated Acid Fluorides

, 2016
Herein we report the first all-carbon N-heterocyclic carbene-catalyzed (4 + 2) cycloaddition. The reaction proceeds with α,β-unsaturated acid fluorides and silyl dienol ethers and produces 1,3-cyclohexadienes with complete diastereocontrol (dr >20:1 ...

Synthesis of 2-Amino-2-Deoxy Sugars via Boron-Catalyzed Coupling of Glycosyl Fluorides and Silyl Ether Acceptors

Whereas aminosugars are an important component in a variety of bioactive molecules, their stereoselective formation is made challenging by the Lewis basic nature of amino substituents.
