Acid-catalyzed synthesis of α,β-disubstituted conjugated enones by a Meyer-Schuster-type rearrangement in allenols

摘要

A novel, direct and simple methodology to gain access to α,β-disubstituted conjugated enones from α-allenols in a sustainable metal catalysis context, considering the inexpensiveness and environmentally friendliness of iron(III) species and protons, has been developed.
