Current Research

    Pheromone Biosynthesis

    This research, conducted in collaboration with Dr. Jay Yoder of the Biology department, seeks to determine the molecular origin of 2,6-dichlorophenol (2,6-DCP), the only known sex pheromone of the American dog tick, Dermacentor variabilis (Say).  Our approach to this investigation involves the use of instrumentation and techniques commonly utilized in modern chemical research laboratories, including GC-MS, NMR and the preparation of non radioisotope containing compounds.  The project also involves quantification of the ability of 2,6-DCP mimics to elicit biological behavior.  Once the production pathway of 2,6-DCP is determined, alterations of the biosynthesis of these chemical cues (i.e.- sex pheromones) that modulate mate attraction could serve as an effective mechanism for control of the species.  This research is supported by a grant from the Merck/AAAS Undergraduate Science Research Program.

    Protective Groups in Organic Synthesis

    The ability of an organic chemist to efficiently carry out a series of synthetic steps, beginning with a single compound, depends in part on the avoidance of undesirable side reactions.  While many organic reactions take place with greater than 80% yield of desired product under controlled conditions, a series of 5 steps of  this efficiency will result in an overall yield of  33%, or a loss of 67% of the initial material.  To avoid this "loss of yield," it is often prudent to protect portions of the molecule from undesired transformation.  In this research, methods to protect carbon-carbon double bonds are being investigated.
