Abstract

Abstract One-step chemical conversion of flavanones into isoflavones by use of thallium trinitrate (TIN) is reported, and the mechanism of a 2, 3-aryl migration in this reaction is discussed in relation to in vivo rearrangement process of flavanone precursors in the isoflavone biosynthesis.
