Microwave-assisted preparation of azachalcones and their N-alkyl derivatives with antimicrobial activities
(Taylor & Francis Ltd, 2014)
Two new azachalcones were prepared by both Claisen-Schmidt condensation and a simple environmentally trendy microwave-assisted method. Ten new N-alkyl (C-6,C-8,C-10,C-12,C-14)-substituted azachalconium bromides (3a-e, 4a-e) ...
