Synthesis of triazole-fused tetracyclic glycosides in aqueous medium: application of nanodomain cubic cuprous oxide as reusable catalyst in one-pot domino Sonogashira-cyclization
摘要:
An environmentally benign one-pot procedure has been developed for the syntheses of triazole-fused tetracyclic glycosides in aqueous medium. The two step one-pot synthesis involves Sonogashira reaction between azido-alkynes and aryl halides followed by intramolecular 1,3-dipolar cyclization using cubic cuprous oxide nanoparticles as reusable catalyst, under aerobic condition. The method excludes the use of any surfactants or additional ligands as stabilizing agents. The catalyst could be used up to three recycles without any loss of catalytic activity. The method has a broad perspective for the synthesis of medium size ring systems. (C) 2015 Elsevier Ltd. All rights reserved.

flavone MAO inhibitor studied is Az2k19 (1.6 mum for MAO-A, 2.1 mum for MAO-B), while Az1k15 and Az2k15 displayed better selectivity toward MAO-B (SI > 10). Docking studies are in accordance with our hypothesis that these inhibitors are most likely located at both the substrate cavity and the "aromatic cage". Our results show that it is considerable to develop new MAO inhibitors from C6 substitution of flavone
