Pseudo five-component process for the synthesis of functionalized tricarboxamides using CuI nanoparticles as reusable catalyst
摘要:
An efficient and multicomponent method has been developed for the synthesis of functionalized tricarboxamides at room temperature using CuI nanoparticles as catalyst. This method involved five-component coupling reactions of Meldrum's acid, isocyanides with aromatic aldehydes and amines at room temperature. Atom economy, wide range of products, excellent yields in short time and mild reaction conditions are some of the important features of this protocol. Notably, this catalyst could be recycled and reused for several times without significantly decreasing the catalytic activity. (C) 2013 Javad Safaei-Ghomi.

The reaction between Meldrum's acid and aryl aldehydes with alkyl isocyanides in the presence of two equivalents of aniline in microwave conditions provided a simple and efficient one-pot route for the synthesis of triamide derivatives in good yields. The present method does not involve any hazardous organic solvent. Therefore, this procedure could be classified as green chemistry.

An efficient one-pot procedure has been proposed for the synthesis of compounds containing three carboxamide groups or one carboxamide and two ester groups. The procedure is based on three-component condensation of alkyl isocyanides with 5-alkylidene- or 5-arylmethylene-substituted Meldrum's acids in the presence of such nucleophiles as phenols and amines.
