The strength of the Lewis or Brensted acids controls the formation of either β,γ-disubstituted-α-methylene-γ-butyrolactones or γ-substituted-α-alkylidene-γ-butyrolactones via the lactonization or oxonia cope rearrangement-lactonization, respectively, of t
Reactivite d'organozinciques allyliques β-fonctionnels γ-substitues. Preparation d'α-methylene γ-butyrolactones β- et γ-substituees

Stable organozinc compounds derived from alkyl 3-alkyl 2-(bromomethyl) propenoates reacted with ketones and aldehydes to give α-methylene γ-butyrolactones in excellent yields.Different reaction parameters were studied and some transition states were proposed.
