Synthesis of Glycomimetics by Diastereoselective Passerini Reaction

The Journal of Organic Chemistry, 2018
We describe the utilization of bis-isopropylidene-protected d-fructose-derived aldehyde in the Passerini reaction with various acids and isocyanides. A library of densely functionalized glycomimetics bearing up to 3 carbohydrate units was obtained in high yields and diastereoselectivities.

Catalytic Enantioselective Passerini Three‐Component Reaction

Angewandte Chemie International Edition, 2007
A [(salen)-AlIIICl] complex catalyzes the Passerini three-component reaction of an aldehyde, a carboxylic acid, and an isocyanide to afford alpha -acyloxyamides, e.g., I, with good to excellent enantioselectivity. A variety of nonchelating substrates can be used to generate the versatile chiral products. [on SciFinder (R)]

Phosphoric Acid-Catalyzed Asymmetric Classic Passerini Reaction

Journal of the American Chemical Society, 2015
An efficient enantioselective classic three-component Passerini reaction with a broad substrate scope in the presence of a chiral phosphoric acid catalyst has been developed. This represents the general example for classic three-component Passerini reaction with good to excellent enantioselectivies involving aromatic aldehydes and the bulky ...

Solvent‐Free Passerini Reactions

Synthetic Communications, 2008
The influence of the substrate structure and concentration on the yield of the Passerini reaction was studied. A new, solvent-free methodology for a convenient preparation of alpha-acyloxyamides 4 was established and compared to the classical methodology. A higher reaction yield was obtained in shorter time, especially in the case of aromatic aldehydes.
