Chemical synthesis has been described as a central science. Its practice provides access to the chemical structures of known and/or designed function. In particular, human health is greatly impacted by synthesis that enables advancements in both basic science discoveries in chemical biology as well as translational research that can lead to new therapeutics. To support the chemical synthesis needs of investigators across campus, the Vanderbilt Institute of Chemical Biology established a chemical synthesis core as part of its foundation in 2008. Provided in this Review are examples of synthetic products, known and designed, produced in the core over the past 10 years.

Herein, porous SnO microspheres in a three-dimensional (3D) hierarchical architecture were successfully synthesized via a facile hydrothermal route utilizing d-(+)-glucose and cetyltrimethylammonium bromide (CTAB), which act as reducing and structure-directing agents, respectively. Controlled adjustment of the CTAB to glucose mole ratio, reaction temperature, reaction time, and the calcination parameters all provided important clues toward optimizing the final morphologies of SnO with exceptional structural stability and reasonable monodispersity. Electron microscopy analysis revealed that microspheres formed were hierarchical self-assemblies of numerous primary SnO nanoparticles of ∼3-8 nm that coalesce together to form nearly monodispersed and ordered spherical structures of sizes in the range of 230-250 nm and are appreciably porous.

Polyphenols, natural compounds abundant in phenolic structures, have received widespread attention due to their antioxidant, anti-inflammatory, antibacterial, and anticancer properties, making them valuable for biomedical applications. However, the green synthesis of polyphenol-based materials with economical and environmentally friendly strategies is of great significance. In this study, a multifunctional wound dressing was achieved by introducing polyphenol-based materials of copper phosphate-tannic acid with a flower-like structure (Cu-TA NFs), which show the reactive oxygen species scavenging performance.

GlcNAc-1,6-anhydro-MurNAc is a key peptidoglycan elongation terminator of biological and medicinal importance. Herein, we present a concise approach to this molecule in 12 steps with an overall 25% yield using d-glucosamine as the sole starting material. Our synthesis features the formation of a 1,6-anhydro-MurNAc building block by an intramolecular glycosylation and the selective conversion of the phthalimido group of the MurNPhth moiety, paving the way for antibiotics with a new killing mechanism by targeting bacterial transglycosylase.
