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.

2-Methylene-4-butyrolactones were conveniently synthesized by treatment of an aldehyde with 2-carboethoxyallyl(-ic) bromide and metallic tin (and aluminium) in good yields.Protolichesterinic acid was synthesized by employing the method.
