RESEARCH INTERESTS

Organic Chemistry
Dr. Oh's research is the development of new methods and strategies for organic synthesis. These methods will be applied to undertake efficient syntheses of complex naturally occurring molecules, particularly those with biological activity and potential use in medicine or medical research. One of Dr. Oh's goals is to develop and apply the hetero Diels-Alder reaction to natural product synthesis. The targets of his current interests are indole alkaloids, starting with ergot alkaloids, and histrionicotoxins. Another project involves the development of chiral Lewis acids that can catalyze and induce asymmetry in organic transformations. The emphasis in on transformations that have been shown to be effective in the synthesis of complex natural products.
