Rh-catalyzed cyclohydrocarbonylation provides a powerful tool for preparation of azabicyclo[X.Y.0]alkane amino acid. These conformationally restrained dipeptide derivatives serve as peptidomimetics and enzyme inhibitors. The scope of this process using various substitutents and ring combinations will be presented. All three stereocenters in the azabicyclo[4.4.0] system can be completely controlled. A plausible mechanism that can accommodate the extremely high diastereoselectivity will be proposed.
