title: A concise formal total synthesis of TMC-95A/B proteasome inhibitors.
abstract: [reaction: see text] A formal total synthesis of proteasome inhibitors TMC-95A/B is described. The synthesis features a stereoselective modified Julia olefination and a diastereoselective dihydroxylation to construct the highly oxidized tryptophan residue.
