چکیده مقاله :
Acridine-1,8-diones as the most emerging fused 1,4-DHP molecules, have broad applications in the field of bio-organic, pharmaceutical, material, industrial, and synthetic organic chemistry. The presence of N-heteroatom, acridine ring skeleton and wide possibilities of diversified substitution, make it a ubiquitous heterocycle in many areas of life [1,2]. The use of solid acid catalysts simplified the reaction conditions in terms of product, selectivity, reaction time, recycling of the catalyst and isolation of the products. To this regard, the green pseudo-four-component synthesis of the acridine-1,8-dione in the presence of carboxylated multiwalled carbon nanotubes (MWCNTs) is presented. Carbon nanomaterials are one of the goals of green chemical pathways. Particular physical properties such as high oxidation stability, good chemical inertness, high surface area, and unusual electron conductivity, have made carbon nanomaterials as good supports for organic synthesis catalysts. [3]. In this study, the MWCNTs were carboxylated by a new method and used as solid acidic catalyst for the green synthesis of acridine-1,8-dione derivatives through the reaction of dimedone, ammonium acetate and various aldehydes in water (Scheme 1). Short reaction times, clean reaction profiles, and high-yield of products are the advantages of this method.
