An efficient and facile synthesis of flavanones catalyzed by N-methylimidazole [PDF]
Journal of the Serbian Chemical Society, 2013 N-Methylimidazole used as an efficient catalyst for the cyclization of 2’- hydroxychalcones to the corresponding flavanones in DMSO was investigated. The scope of this process has been studied and various flavanones were obtained exclusively in good ...

Flavanones from Vernonia diffusa [PDF]
Journal of the Brazilian Chemical Society, 1999 From the methanolic extract of the wood of Vernonia diffusa two flavanones were isolated and identified: hesperidin and a new flavanone, 3'-methylhesperetin (homoesperetin) and sucrose, which was identified as its acetyl derivative. The homoesperetin was
