A new method is reported for constructing alpha -methylene- gamma -butyrolactone moiety under neutral, anhydrous conditions. Olefin-dibromocarbene adducts were transformed into methyl 1-(dimethylaminoethyl)cyclopropanecarboxylates. Treatment with trimethylsily iodide followed by thermolytic distillation of the crude products gave alpha -methylene gamma -butyrolactones with high regio- and stereoselectivity.
