REACTION OF 1,5-DIARYL-3-HYDROXY-4-METHYLSULFONYL-3-PYRROLIN-2-ONES WITH UREA, HYDRAZINE, ETHYLENEDIAMINE, AND <i>o</i>-PHENYLENEDIAMINE

Abstract

With urea 1,5-diaryl-3-hydroxy-4-methylsulfonyl-3-pyrrolin-2-ones form the 3-amino derivatives of pyrrolones. In reactions with hydrazine hydrate and ethylenediamine the corresponding salts are formed. With ethylenediamine at 180-185°C the double salt of 3-hydroxy-4-methylsulfonyl-1,5-diphenyl-3-pyrrolin-2-one forms N,N′-di(4-methylsulfonyl-1,5-diphenyl-3-pyrrolin-2-on-3-yl)-ethylenediamine. The reaction with o-phenylenediamine gives 2,3-diaryl-4-methylsulfonylpyrrolo-[2,3-b]quinoxalines.
