Research Interests:

The Hamme research group is interested in the synthesis of biologically active heterocyclic containing natural products and their synthetic analogues.  Our synthetic approach usually incorporates a 1,3-dipolar cycloaddition reaction of a 1,3-dipole with a functionalized alkene or alkyne to afford the corresponding heterocyclic compound which usually serves as a precursor to a more complex ring system.  Our research group is also interested in the use of pure water as a reaction medium for organic synthesis.
