Analogs of silybin and dehydrosilybin have been obtained from 1,4-benzodioxane derivatives of chalcones, and their structures have been shown by their PMR and IR spectra.
Synthetic analogs of natural flavolignans. XII. Synthesis of 3,5-diarylsubstituted pyrazolines based on 1,3-benzodioxane and 1,4-benzodioxane chalcone analogs
3,5-Diarylsubstituted pyrazolines were synthesized by reaction of 1,3-benzodioxane and 1,4-benzodioxane chalcone analogs with hydrazine hydrate. The structures of the products were confirmed by PMR spectroscopy.
