'Dihydromorin pentaacetate', mp 192 deg, was shown to be 5,7,2',4'-tetraacetoxyflavone.Oxyresveratrol with acid or MS (probe) gave resorcinol and 7-(3,5-dihydroxyphenyl)naphthalen-1,3-diol.

Solvent effects on the stereochemistry in the sodium borohydride reduction of (+/-)-flavanonols have been examined.The effects observed for the (+/-)-flavanonols with 5-OMe in 2-propanol, dioxane and methanol are explainable by the differences between the steric interactions inherent in the product-like transition states A and B.It has been also found that 5-OAc peculiarly affects the stereochemistry in the reduction to produce the (+/-)-catechin-type compounds in a one-pot process.The solvent and temperature effects are examined using a model analogous to the above.
