✦ Synopsis

A convenient new method for the synthesis of polysubstituted 2-imidazolidinones has been established involving the reaction of 4-alkylamino-2-aryl-2-oxazolines with arylsulfonyl isocyanates. It has been applied successfully in preparing previously unknown 3-alkyl-4-aroylamino-l-arylsulfonyl-2-imidazolidinones in high yields.

A novel heterocycle-heterocycle inter-conversion is reported. It enables direct and efficient syntheses of either polysubstituted 2-arylimino-1,3-oxazolidine or 2-arylimino-1,3-thiazolidine hydrochlorides by a one-pot treatment of 4-amino-2phenyl-2-oxazolines with arylisocyanates or arylisothiocyana
