Carbozincation of dipolar trimethylenemethane. A new route to functionalized organozinc reagents
Dipolar trimethylenemethane species, thermally generated from 2,2-dialkoxy-1-methylenecyclopropane, reacts with a dialkylzinc reagent to generate an allylic zinc reagent, which. F then reacts in situ with a carbonyl compound to give a hydroxy acetal product as the result of coupling of the three reactants.
