The action of NaBH4 on some typical isoflavones yields isoflavan-4-ols in 70–85% yields. 2-Methylisoflavones are resistant to this reduction. The isoflavan-4-ols undergo dehydration to isoflavens in presence of protonic reagents suggesting a quasi-trans relationship between the quasi-equatorial 4-OH and 3-H, proposed by Michelie et al. and based on NMR evidence.
