One-Pot Synthesis of 1,8-Dioxodecahydroacridines and Polyhydroquinoline using 1,3-Di (bromo or chloro)-5,5-Dimethylhydantoin as a Novel and Green Catalyst under Solvent-Free Conditions. J. Mex. Chem. Soc [online]. 2013, vol.57, n.4, pp.290-297. ISSN 1870-249X.

Abstract Solvent-free, one-pot synthesis of polyhdroquinoline and 1,8-dioxodecahydroacridine derivatives have been described via Hantzsch condensation of various aldehydes, ammonium acetate with (i) cyclic 1,3-dicarbonyl compounds and ethyl acetoacetate and (ii) cyclic 1,3-dicarbonyl compounds (2 mmoles) in a very simple, efficient, and environmentally benign method using 1,3-(dibromo or dichloro)-5,5-dimethylhydantoin as a cheap, non-toxic and neutral catalyst with up to excellent yields.

Palavras-chave : Aldehydes; cyclic 1,3-dicarbonyl compounds; ammonium acetate; ethyl acetoacetate; green catalyst; solvent-free conditions; one-pot synthesis.
