Abstract
In the presence of powdered lead, the reaction of aldehydes and alpha- bromomethylacrylate (or alpha-bromomethylacrylic acid) can be carried out under mild condition, the products 4-hydroxy-2-methylenebutanoates (or 4-hydroxy-2-methylenebutanoic acids) can be easily converted to a lpha- methylene-gamma-butyrolactones in the presence of CF3COOH.
