Throwback Thursday: The first preparative non-heme iron oxidation catalyst achieved in the Jacobsen group at Harvard in 2001. MCW with her undergraduate student Abigail Doyle of

pictured in front of their hood where the discovery was made.
Happy 80th birthday to one of my scientific role models and heroes, K. Barry Sharpless. Your work and path continue to inspire scientists who aspire to discover rare and disruptive reactivity.
The total synthesis and structural elucidation of palytoxin by Kishi stands as one of the greatest achievements of science demonstrating that even the most complex structures in nature (71 stereochemical elements) can be made through chemical synthesis. RIP Prof. Kishi
My Ph D advisor, Gary H. Posner (1943-2018), had this C. Coolidge quote hanging in his office. With time, experience, and walking a little in his shoes, I have come to appreciate the wisdom of these words. MCW
Throwback Thursday:
@MCWhiteGroup
are so proud of Ken Fraunhoffer, first graduate in group, who is now a scientific director
@bmsnews
! He discovered the first preparative allylic C—H amination .
Check out Aliphatic C—H Oxidation notes updated by Hannah Way and Jake Weaver. If you would like the powerpoint slides for teaching, please email thewhitegroup

Awesome to host Sarah Reisman as our 2023 Fuson lecturer. She gave two powerful talks that showcased the power of total synthesis to inspire transformative new methodology.
Interested in P450s vs Mn(CF3PDP) oxidations in carbocyclic N-heterocyclic drugs & describing substrate scope quantitatively? Check out PNAS paper from Rachel, Jake & Jinho of

Dave Evans solved the polyketide problem. Today, students cannot imagine how polyketides were made before the Evans aldol. It simplified the problem of constructing stereochemically defined polyols so that scientists could them to answer other important questions. RIP

When I started as an Assistant Prof. At Harvard , Prof. Evans gave me this advice: “You should be aiming far beyond tenure “. The same can be said for a PhD.
Practicing gratitude means recognizing the good that is already yours. This Thanksgiving, I feel grateful for an amazing group of students who in addition to being brilliant, creative, and hard-working, face difficult times with optimism, resilience and adaptability.
Excited to welcome Marc Hartmann to MCWhite group! Marc is from New Jersey and attended Rutgers University where he worked with Dr. Zoltan Szekely on synthesis of antibody-drug conjugates. After, he worked 2 years in sunny San Diego at Avidity Biosciences on RNA bioconjugations.

Happy 80th birthday DAE. You taught a generation of chemists the power and beauty of physical organic chemistry through your iconic Chem 206 and impacting research. I use what I learned from you every day in how I think about chemical reactivity and selectivity.

Excited to welcome Emma Mize the MCWhite group! Emma attended SLU for her undergrad where she worked in the Demchenko lab doing research in carbohydrates. As a St. Louis native, she is a big fan of the STL City soccer team. Emma is also an avid baker!
Throwback Thursday: Teaching organometallics and reminded of two seminal (and often overlooked papers): in 1955 and 1956 Shunsuke Murahashi of Osaka University reported the first examples of directed, catalytic aryl C—H functionalizations
An honor to be the Seymour Rothchild Distinguished Student Invited Lecturer at Rochester Chemistry. Awesome to meet Cay McNichol my host and the other remarkable students in group of our own Shauna Paradine
@paradinelab
Great to welcome Joseph Clark (of the Clark-White catalyst) back to UIUC to give a great talk about the pioneering work he is doing on precision deuteration at Marquette University!
