Uncontrolled Sensitization in Asymmetric Photocatalysis

Steven worked with Zeb Girvin (Miller group), Laura Cotter and Hyung Yoon (Mayer group) in a fun three-lab collaborative project on asymmetric [2+2] photocycloadditions of acyclic vinylpyiridines, now up at JACS. The reaction involves an unusual mechanism for an asymmetric excited-state photoreaction where the chiral catalyst influences the rate of a step after the initial sensitization step.
