DESCRIPTION:Abstract:\n\nPhotochemistry is intriguing as a synthetic tool b
 ecause the absorption of light by an organic molecule results in the forma
 tion of exceptionally energetic reactive intermediates that can react in w
 ays that are inaccessible to ground-state molecules. However\, this high r
 eactivity is also a challenge for stereoselective synthesis: control over 
 the stereochemistry of photochemical reactions\, particularly using enanti
 oselective catalysts\, has been a long-standing challenging synthetic prob
 lem with few general solutions. We recently developed a strategy that util
 izes privileged chiral Brønsted acid scaffolds to control both the absolut
 e and relative stereochemistry of complex [2+2] photocycloadditions. These
  reactions have enabled a general\, concise\, and stereocontrolled strateg
 y for the synthesis of the truxinate and truxillate natural products.\n\n 
 \n\n \n\nBio:\n\nTehshik Yoon is a Professor of Chemistry at the Universit
 y of Wisconsin–Madison. He received his bachelor's degree in chemistry fro
 m Harvard University\, where he performed undergraduate research with Prof
 . David Evans\, and his master's degree from Caltech under the supervision
  of Prof. Erick Carreira. His Ph.D. thesis with Prof. David MacMillan\, fi
 rst at Berkeley and then at Caltech\, focused on the development of chiral
  Lewis acids for enantioselective Claisen rearrangements. After finishing 
 graduate school in 2002\, he became an NIH postdoctoral fellow in the labo
 ratory of Prof. Eric Jacobsen at Harvard\, where his research involved the
  development of a hydrogen bond-donating catalyst for asymmetric nitro-Man
 nich reactions.\n\nTehshik has been on the faculty at UW–Madison since 200
 5. His research group has broad interests in organic synthesis and catalys
 is. In particular\, the Yoon group has been pioneering the use of transiti
 on metal photocatalysts in synthetically useful transformations promoted b
 y visible light. Tehshik's efforts in teaching and research have earned hi
 m a variety of prestigious of awards\, including an NSF CAREER Award (2007
 )\, the Research Corporation Cottrell Scholar Award (2008)\, the Beckman Y
 oung Investigator Award (2008)\, the Amgen Young Investigator Award (2009)
 \, an Alfred P. Sloan Research Fellowship (2009)\, an Eli Lilly Grantee Aw
 ard (2011)\, a Friedrich Wilhelm Bessel Award from the Humboldt Foundation
  (2015)\, and an ACS Cope Scholar Award (2019).\n
