A full account of the total syntheses of proteasome inhibitors TMC-95A and -B is provided. A key feature of the syntheses involved installation of a cis-propenylamide moiety by a thermal rearrangement of an α-silylallyl amide. The scope and mechanism of the enamide-forming reaction are discussed. Also provided are some preliminary results from SAR studies. It was found that simplified analogues can retain the full potency of proteasome inhibition.

A mild and chemoselective hydrogenation method for a variety of reducible functional groups distinguishing front aliphatic and aromatic' benzyl ethers was accomplished by the addition of an appropriate nitrogen- containing base to the Pd/C-catalyzed hydrogenation system.
