Research Synopsis

We currently have two research themes: (1) Development of organoiron chemistry for applications in organic synthesis, and (2) Development of organocatalysts for asymmetric aldol reactions.

The discovery and development of new reactions is a very exciting outcome in organic synthesis research. Our group has been fortunate to discover a number of new reactions (all by accident!), some of which are illustrated here.


This [6+2] ene-type reaction was discovered by graduate student Mark Zettler, the example given here showing how a densely substituted multicyclic structure can be constructed, that relates to the sesquiterpenoid verrucarol. Subsequent work by graduate student Xiaolong Wang resulted in a two-step procedure for stereospecific conversion of a readily prepared cyclohexadiene into a molecule that has much of the structure in place for synthetic approaches to the complex alkaloid gelsemine. Xiaolong also developed a sereocontrolled asymmetric ene cyclization that uses dynamic diastereoselectivity during the ene coupling process:


Recent work on this ene reaction has shown that the pendant alkene can be replaced by an aldehyde, which could provide an approach to compounds such as spirostaphylotrichin A:


Organocatalyzed Asymmetric Aldol Reactions

We have recently developed several new proline-derived organocatalysts for use in asymmetric aldol reactions. The design principle uses an anthranilic acid core as a structural template to induce a reverse turn and give a chiral binding pocket for the substrates, as exemplified here:
