  Reaction of N-arenesulfonyl-1,4-benzoquinone imines with acetylacetone

  摘要：

  N-Arenesulfonyl-1,4-benzoquinone imines reacted with acetylacetone to afford different products, depending on the isolation procedure. Crystallization from polar protic solvents gave N-[4-hydroxy- 3-(2-hydroxy-4-oxopent-2-en-3-yl)phenyl]arenesulfonamides and 6-(2-oxopropyl)-4-(arenesulfonamido)phenyl acetates, whereas N-(3-acetyl-2,6-dimethyl-1-benzofuran-5-yl)arenesulfonamides were isolated by crystallization from nonpolar aprotic solvents.
