| Outline of Research at the Start |
We are seeking to expand the already broad chemical reactivity of carboxylic acids in order to provide rapid access to useful building blocks for chemical synthesis. To mediate this process, the novel catalyst 'DATB' will be re-purposed from amide bond synthesis to C-C bond formation reactions.
|
| Outline of Final Research Achievements |
We had initially anticipated that the DATB catalyst could be used in tandem with transition metals to access novel reaction pathways. However. despite countless attempts over the course of a year, we we never successful in achieving this goal. As such, we changed modified our plan to exploring how changes to the structure of DATB could alter its reactivity. One of our ideas was to synthesize, characterize and test the catalytic activity of N(BOH)2-containing molecules. While this moiety is structurally similar to DATB, no synthetic pathways to produce it were present in the literature. Fortunately, we were successful in our endevour, producing a shelf-stable compound that was even more catalytically active than the DATB catalyst. The work was published in Org. Lett. (2023, 25, 4, 694-697). This novel catalytically-active moiety likely
provides a novel mode of action for amide activation, which warrants further investigation.

| Academic Significance and Societal Importance of the Research Achievements |
One of the most frequently encountered reactions in chemistry, especially in medicinal chemistry, is that of amide bond formation. The 'traditional' methods to achieve this transformation necessarily occur with concurrent production of waste materials. This project uncovered a new catalytic method.
