A general method for the preparation of α-bromoallenic esters (2) involving the reaction of an acid chloride with a carboxybromomethylenetriphenylphosphorane has been developed.Reaction of these esters with the 4-mercaptoazetidin-2-one (1) gave rise to the 2-alkylidenepenam esters (3).The title compounds, obtained by hydrogenolysis of the corresponding benzyl esters, showed only moderate antibacterial properties.
