method has been established for the installation of both aliphatic and aromatic sidechains and the introduction of deuterium into the chiral methyleneoxazolidinone simultaneously. Efficient coupling of readily available boronic acids with the chiral auxiliary delivers structurally diverse α-deuterated α-amino acidderivatives with a high level of diastereoselectivity and deuteration.
Morphing structural features of HTS-derived chemotypes led to the discovery of novel 2-cyano-pyrimidine inhibitors of cathepsin K with good pharmacokinetic profiles, for example, compound 20 showed high catK potency (IC(50) = 4 nM), >580-fold selectivity over catL and catB, and oral bioavailability in the rat of 52%.
