Synthesis and Characterization of some New Mesoionic 1,3-Thiazolium-5-thiolates via Cyclodehydration and in situ 1,3-Dipolar Cycloaddition/Cycloreversion
Autor: Maria Joaquina Vieira, Aderson de Farias Dias, Alfredo Mayall Simas, Joseph Miller, Petrônio Filgueiras de Athayde Filho, Bruno Freitas Lira
Publikováno v: Molecules, Vol 7, Iss 11, Pp 791-800 (2002)
The title compounds were synthesized from C-aryl-N-methylglycines by Naroylation followed by a cyclodehydration to form the corresponding 1,3-oxazolium-5-olates. These were not isolated but converted to the title compounds by an in situ 1,3-dipolar c
