▼a Photochemical activation of organic molecules is of wide interest to synthetic chemists, as electronically excited organic species often have unique and orthogonal modes of reactivity when compared to their ground state analogs. However, most organic molecules are invisible to all but high-energy UV light, dramatically limiting the scope of viable substrates. Recent work in the Yoon lab has focused on overcoming this limitation by exploiting visible light-absorbing transition metal photosensitizers-species that are capable of activating organic molecules via triplet energy transfer. This mode of activation takes advantage of the long-lived triplet state of these photosensitizers by coupling their relaxation with the excitation of an organic substrate to its triplet state. The work presented herein will describe how this strategy was employed in the generation of triplet nitrenes from azides for the development of a chemoselective olefin aziridination methodology. Further application of this strategy has led to the development of a triplet sensitized [2+2] cycloaddition of vinyl boronates, leading to densely functionalized cyclobutane building blocks. Additional studies have shown that this vinyl boronate handle can be further utilized for enantioselective construction cyclobutane core. |
