摘要：
Methyl-2-bromomethylprop-2-enoate reacts with benzaldehyde and with salicylaldehyde via its Sn and Zn complexes under aqueous conditions to form alpha-methylene-gamma-lactones in high yields. In the case of salicylaldehyde X-ray analysis proves conclusively formation of a five- rather than a seven-membered ring. Under the above conditions 2-bromomethyl-3-phenylprop-2-enoate does not afford any cyclic products.
