Abstract

Wessely-Moser rearrangement reaction of 5,7-dihydroxychromone derivatives with an isopentyl side chain at C-6 or C-8 position was examined. All reactions gave 8-isopentylchromone derivative predominantly as rearrangement product. Kinetic analysis of the one-sided rearrangement reaction revealed that the reaction depends on stability of a flavylium cation originated from 8-isopentylchromone derivative.
