Chemical biology encompasses the study and manipulation of biological system using chemistry, often by virtue of small molecules or unnatural amino acids. Much insight has been gained into the mechanisms of biological processes with regards to protein structure and function, metabolic processes and changes between healthy and diseased states. As an ever expanding field, developing new tools to interact with and impact biological systems is an extremely valuable goal. Herein, work is described towards the synthesis of a small library of heterocyclic-containing small molecules and the mechanistic details regarding the interesting and unexpected chemical compounds that arose; an alternative set of non-toxic copper catalyzed azide-alkyne click conditions for in vivo metabolic labelling; and the synthesis of an unnatural amino acid for further chemical modification via [3+2] cycloadditions with nitrones upon incorporation into a peptide of interest. Altogether, these projects strive to supplement pre-existing methodology for the synthesis of small molecule libraries and tools for metabolic labelling, and thus provide further small molecules for understanding biological systems.
