Work in our Laboratories has led to a number of new approaches for the construction of the a-methylene lactone structural unit employing O-hydroxymethyl,' a-carboxylic acid,2 and (II-phenylseleny13 lactones. Continued interest4 in methods for the synthesis of a-methylene lactones prompts us to repor
