Lewis acid catalyzed vinylogous Mukaiyama–Michael (VMM) reactions between 2-(trialkylsilyloxy)furans 1 and α,β-unsaturatedcyclic enones 2 or oxo esters 4 have been investigated. Both substrates proved to be useful Michael acceptors in the title reaction, giving the butenolides 3 and 5 in good yields. A comparative study between the α,β-unsaturatedcyclic enones 2 and the oxo esters 4 as Michael acceptors
