Abstract: The crystal structures of racemic mixtures of three new flavanone-hydrazones are reported: (±,E)-N′-[5,7-dihydroxy-2-(4-hydroxyphenyl)chroman-4-ylidene]-2-(naphthalen-1-yl)acetohydrazide ethyl acetate monosolvate, (±,E)-N′-[5,7-dihydroxy-2-(4-hydroxyphenyl)chroman-4-ylidene]-4-hydroxybenzohydrazide ethanol monosolvate and (±,E)-N′-(6-methoxy-2-phenylchroman-4-ylidene)-2-(naphthalen-1-yloxy)acetohydrazide. All three hydrazones are in the E isomeric form and exhibit a pucker at… read more here.
