"Pericyclic Reactions: Theory, Mechanisms, Dynamics, and Role in Biology"
Dr. James D. ('30) and Julia P. Morrison Lectureship
K. N. Houk,

Pericyclic reactions were defined by Woodward and Hoffmann in the 1960s. Pericyclic reactions are concerted processes involving a cyclic reorganization of bonding. I will describe computational studies focusing on four recent discoveries: 1) defining mechanisms of these reactions in terms of dynamics of bonding changes; 2) finding ambimodal polypericyclic transition states that give more than one product; 3) explaining orbital symmetry forbidden reactions that nevertheless occur readily; and 4) identifying the role of pericyclic reactions in biosynthesis, catalyzed by a class of enzymes that we have named pericyclases.
