Abstract
Substituted alpha-methylene-beta-lactones (2) were prepared in two ste ps, from substituted propargyl alcohols, by hydrocarboxylation under a tmospheric pressure of CO in the presence of nickel cyanide under phas e-transfer conditions. The alpha-methylene-3-hydroxypropanoic acid der ivatives so formed (12-40% yield), were cyclized with mesyl chloride ( 22-56% yield).
