Convenient synthesis of 5-(Arylamino(Alkylthio)Methylene)-2,2-Dimethyl-1,3-Dioxane-4,6-Diones and 2-Arylthio-4-Quinolones

Abstract

Meldrum's acid reacted with an aryl isothiocynate and alkyl halides to afford the 5-(arylamino(alkylthio)methylene)-5-methylthio-2,2-dimethyl-1,3-dioxane-4,6-diones and the compounds underwent thermal cyclization to give the 4-2-arylthio-4(1H)-quinolones

Keywords
