Abstract

Abstract The action of ammonium acetate on 5-arylidene-3-phenyl-2- methylmercaptohydantoins 1g, h in acetic acid led to the formation of the 5-arylidene-3- phenylhydantoin derivatives 4a, b. In absence of a solvent, ring opening and rearrangement took place with the formation of the 5-arylidene-N 2-phenylglycocyamidine derivatives 7a-c. Compounds 7a-c reacted with methyl iodide to afford the corresponding 3-methyl ...
