The account summarizes the development of the ester dienolate [2,3]-Wittig
rearrangement as a versatile synthetic tool for the construction
of highly substituted 3-alkoxycarbonyl-3-hydroxy-substituted 1,5-hexadienes.
Furthermore, the account provides an insight into a novel sequential
pericyclic reaction employing the 1,5-hexadienes accessible through
the ester dienolate [2,3]-Wittig rearrangement.
