A concise synthesis of the β-lactone esterase inhibitor valilactone (1) is reported. This synthesis employs the stereoselctive preparation of a π-allyltricarbonyliron lactone complex (7) that on oxidation with cericammoniumnitrate, affords an appropriately substituted β-lactone (9) which was transformed to (1).
