REGIOSPECIFIC RING CLEAVAGE OF α,β-EPOXYSILANES TO FORM TRANSITION METAL ENOLATE INTERMEDIATES
Molybdenum(II) acetate dimer or titanium(IV) i-propoxide induced regiospecific ring cleavage of α,β-epoxysilanes to form the enolate intermediates, which reacted with aldehydes to give the corresponding α,β-unsaturated carbonyl compounds.
