Description:About the Seminar:\n\nThe Nacsa Group uses electron transfer te
 chniques to address challenges in organic synthesis. Our lab works in two 
 main areas. The first uses electrochemistry to develop new approaches for 
 dehydration reactions\, such as the synthesis of amides and esters from ca
 rboxylic acids\, with an emphasis on catalysis. Dehydrative transformation
 s are workhorse operations in pharmaceutical R&amp\;D\, but owing to the w
 asteful reagents overwhelmingly used to accomplish them\, industry has lon
 g called for methods that avoid these reagents. We have identified new ele
 ctrochemical strategies for the substitution of carboxylic acids that meet
  these demands. Our second program leverages radical-mediated migration ev
 ents\, usually initiated by photoinduced electron transfer\, as key design
  elements in complexity-generating transformations. We have shown that ole
 fin difunctionalizations underpinned by this approach can access product c
 lasses and achieve stereoselectivities that have otherwise proven challeng
 ing or impossible. More recently\, we have discovered conceptually novel a
 nd synthetically enabling methods for the amination of aromatics and the s
 tereoselective a-functionalization of carbonyls.\n\nAbout the Speaker:\n\
 nEric was born in Toronto\, Ontario\, Canada\, and grew up nearby in Kings
 ton\, Ontario. He graduated with a BSc in Chemistry from Harvey Mudd Colle
 ge in Claremont\, CA in 2010\, where he worked on the total synthesis of s
 esquiterpene natural products. He received a PhD from Columbia University 
 in 2015\, studying synthetic applications of aromatic ions with Tristan La
 mbert. He finished his training with David MacMillan at Princeton Universi
 ty as an NIH postdoctoral fellow developing light-promoted asymmetric tran
 sformations. Eric began his independent career at Penn State University in
  2019. His lab develops new synthetic methods and has received ACS PRF\, N
 SF CAREER\, and NIH R35 awards. 4:00 pm
