Significance

Clinical trials are underway on salinosporamide for the treatment of cancer as it inhibits the 20S proteasome. An intramolecular aldol reaction converts A into intermediate D (100 g scale) with the simultaneous creation of three stereo­genic centers using Seebach’s self-regeneration of stereogenic centers strategy (D. Seebach, A. R. Sting, M. Hoffmann Angew. Chem. Int. Ed. 1996, 35, 2708).
