  Application of the β-cyclodextrin supramolecules as a green accelerator hosts in one-step preparation of highly functionalised rhodanine scaffolds

  摘要：

  beta-Cyclodextrin (beta-CD) supramolecule was found to be a convenient, green and economical tool in one-pot synthesis of rhodanine scaffolds as a highly efficient mediating agent in aqueous media in which the reaction accelerated to complete in 15min and room temperature. In this work, amines reacted with equimolar ratio of CS2 (not excess ratio of CS2) and then with activated acetylenes in the presence of beta-CD in aqueous media.

  In this work, magnetically separable Fe3O4 nanoparticles were synthesized in the presence of natural K-carrageenan (KCAR) biopolymer to provide Fe3O4@KCAR. FT-IR analysis, scanning electron microscopy (SEM), X-ray diffraction, VSM analysis, and SEM-EDAX were incorporated for the characterization of Fe3O4@KCAR nanocomposite. And then, the first catalytic report of Fe3O4@KCAR with no post-modification was achieved by studying its catalytic activity in the multicomponent reaction of rhodanine synthesis. Based on this study, Fe3O4@KCAR was an efficient, magnetically separable and recyclable, water-dispersible and green catalyst with natural source. This catalyst also showed 9-run recyclability with no significant yield decrease. (C) 2015 Elsevier B.V. All rights reserved.

  Aqueous cetyltrimethylammonium bromide-surfactant micelles were found to be an efficient and rapid reactor system for the synthesis of rhodanine by a three-component reaction of amine, carbon disulfide, and activated acetylene. The advantages of this method are the use of a water medium and a simple and easy workup resulting in a green and direct synthetic method to give excellent yields of rhodanine derivatives.

  Hexafluoroisopropanol dispersed catalytically amount of SBA-15 (HFIP/SBA-15) with organic substrate was found to be an efficient, ultra-fast and waste-free approach for the synthesis of the biologically and pharmaceutically interesting alkyl rhodanines. The advantages of the present method are low catalyst loading, simple procedure, waste-free and direct synthetic entry to excellent yield of rhodanines, high reusability of the catalyst, and short reaction time. Also, the reaction can be performed without activation and modification of the substrates under the neutral conditions. The solid SBA-15 and HFIP could be recovered and reused for recycling.
