NUCLEOPHILIC ATTACK ON 4,6-DIMETHOXY-2-PYRONES; DISCOVERY OF A REMARKABLY FACILE REARRANGEMENT OF THE PYRONES

During the course of mechanistic investigations of nucleophilic attack on 4,6-dimethoxy-2-pyrones, a rapid scrambling reaction has been found between 4,6-dimethoxy-3-methyl-2-pyrone and the corresponding 5-methyl isomer
