Article abstract of DOI:10.1007/BF00629867

The reactions 1,3-benzodioxolane, 1,4-benzodioxane, and 1,5-benzodioxepane analogs of isoflavones with hydrazine derivatives have been studied.It has been found that under the action of hydrazines the new isoflavones recyclize into 3,4-diarylpyrazones.The
