Research Abstract
The Van Vranken group studies and develops chemical reactions in two areas:
peptide reporters of cell function and transition metal-catalyzed carbene insertions.

Our efforts to harness these patterns of reactivity have led to new tools for biology, new tools for synthesis, and new approaches to construction of natural products. Our group has developed concise routes to a range of bioactive natural products that include: AT-2433 A1 and B1; tjipanazoles F1, F2, C1, and C2; phakellistatins 3 and 13; madindolines A and B; corylifolin; and bakuchiol.

Peptide Reprters of Cell Function
Peptides display reactive functional groups that are suseptible to selective modification. Many modifications lead to strong visible fluorescence, for example formation of dityrosine crosslinks and ditryptophan crosslinks discovered by our group. Peptide sequence determines chemical reactivity in much the same way that it determines protein structure. We are identifying sequences that confer selective chemical reactivity towards fluorogenic reagents. An additional goal of our research is to develope selective small molecule reporters of MAP kinase activity.

Transition Metal-Catalyzed Carbene Insertions
We are also enganged in the study of transition metal-catalyzed reactions that lead to insertion of carbon atoms of one atom at a time. We have shown that iron and palladium catalysts can catalyze the addition and rearangment of carbenes, derived from diazo compounds, to allylic and propargylic thioethers. We have extended this work, showing that palladium can catalyze the insertion of carbenes into carbon-halogen bonds
