| Outline of Final Research Achievements |
This research project aimed at the development of new catalytic reactions for the synthesis of b2-amino acids. Readily available, substituted isoxazolidin-5-ones were selected as substrates. The efforts in this project has led to two classes of transformations: direct catalytic asymmetric Mannich-type reactions and traceless CH functionalizations. The former reaction was well suited for the synthesis of complex, linear b2,2-amino acids, whereas the latter was for cyclic b2-amino acids otherwise difficult to obtain. The cyclization process was triggered upon the generation of alkyl nitrene species that has not been documented well in the literature, opening up a new avenue to the chemistry of the reactive intermediate.
