Synthesis of (R)-ar-turmerone and its conversion to (R)-ar-himachalene, a pheromone component of the flea beetle: (R)-ar-himachalene is dextrorotatory in hexane, while levorotatory in chloroform

(R)-ar-Turmerone was synthesized from (4-methylphenyl)acetic acid by employing Evans asymmetric alkylation as the key step. (R)-ar-Turmerone was converted to (R)-ar-himachalene, which was dextrorotatory in hexane while levorotatory in chloroform. Enantiomerically impure (75% ee) (R)-3-(4-methylphenyl)butanoic acid crystallized more readily than the enantiomerically pure one.

Peptidic, non-covalent inhibitors of lysosomal cysteine protease cathepsin S (1 and 2) were investigated due to low oral bioavailability, leading to an improved series of peptidomimetic inhibitors. Utilizing phenyl succinamides as the P2 residue increased the oral exposure of this lead series of compounds, while retaining selective inhibition of the cathepsin S isoform. Concurrent investigation of the P1 and P2 subsites resulted in the discovery of several potent and selective inhibitors of cathepsin S with good pharmacokinetic properties due to the elimination of saturated aliphatic P2 residues.
Organic synthesis in pheromone science
