Acid-Catalyzed Synthesis of alpha,beta-Disubstituted Conjugated Enones by a Meyer-Schuster-Type Rearrangement in Allenols

摘要

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