Reaction of 4,5-dihydroxy-2-imidazolidinones with arylsulfinic acids. Synthesis of 4-arylsulfonyl-2-imidazolinones

Abstract

The reaction of 4,5-dihydroxy-2-imidazolidinones with arylsulfinic acids in water upon heating leads to 4-arylsulfonyl-2-imidazolinones. The formation of such compounds was found to proceed through the loss of a water molecule or sulfinic acid from intermediate 4-hydroxy-5-arylsulfonyl-2-imidazlidinones and 4,5-dihydroxy-2-imidazolidinones. 4-Arylsulfonyl-2-imidazolinones are also formed upon heating glyoxal, urea, and arylsulfinic acids in water.
