Synthesis of d-glycopyranosyl depsipeptides using Passerini reaction
Carbohydrate Research, 2021A protocol based on Passerini multi-component reaction has been developed for facile, efficient and atom economical synthesis of a small library of twenty potential bioactive (2R)-2-(d-glycopyranosyl)-2-acyloxyacetamides using perbenzylated d-glycopyranosyl aldehydes, substituted isocyanides and different aliphatic/aromatic carboxylic acids. All twenty

Solvent‐Free Passerini Reactions
Synthetic Communications, 2008The 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.

Synthesis of Glycomimetics by Diastereoselective Passerini Reaction
The Journal of Organic Chemistry, 2018We 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.

Synthetic Applications of Passerini Reaction
Current Organic Chemistry, 2012Passerini reaction involving an oxo component, an isocyanide, and a nucleophile in a single step to prepare -acyloxy carbox- amide, was first discovered by Passerini about 90 years ago. Various modifications of this reaction have already been developed such as Lewis acids catalysis, in situ oxidation of alcohols to aldehydes, in situ oxidation of ...

Catalytic Enantioselective Passerini Three‐Component Reaction
Angewandte Chemie International Edition, 2007A [(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)]

Homologation of Ugi and Passerini reactions using ynamides
Drug Discovery Today: Technologies, 2018Being important biological and pharmacological units, β-amino amides and β-acyloxy amides have a privileged position in both academia and industry. Developing a methods to prepare them has gained attention. Ynamides, which possess dual nucleophilic and electrophilic properties, are similar to isonitriles. In this review, usage of ynamides in the single
