A 14-step total synthesis of (±)-salinosporamide A (1), a potent inhibitor of the 20S proteasome isolated from the marine bacterium Salinospora tropica, is described. The synthesis is based on a diastereoselective intramolecular aldolisation of a substitu

Acetylation of the N-substituted diethyl aminomalonates 3a-3d with diketene furnished the ring tautomers 6a-6d of the expected acetoacetyl derivatives 5.By treatment with iodine and sodium ethoxide compounds 6a-6d are smoothly converted into the β-lactam
