Bruce H. Lipshutz

Bruce H. Lipshutz (born 1951) is an American chemist. He is a professor at the University of California, Santa Barbara.[1]

Biography

Lipshutz received his undergraduate degree in chemistry from Binghamton University in 1973. His graduate work was supervised by Harry H. Wasserman at Yale. After a PhD degree in 1977, he spent two years at Harvard as a post-doctoral researcher in the group of Nobel Laureate E. J. Corey. Soon after, he accepted a position of Assistant Professor at UCSB rising to the ranks of Professor in 1987. He has received the Alfred P. Sloan Foundation Fellowship and the Camille & Henry Dreyfus Teacher-Scholar Award. In 2011 he was awarded Presidential Green Chemistry Award.[2] He is Co-founder of Zymes LLC.[3]

Contributions

Reagents

Aqueous Micellar Catalysis using TPGS-750-M[4] and Nok.[5]
Sustainable Palladium catalysis.[6][7]
2-(Trimethylsilyl)ethoxymethyl chloride: hydroxyl protecting group, selectively cleaved with fluoride ion under mild conditions.[8]
Di-(4-chlorobenzyl)azodicarboxylate (DCAD): recyclable and convenient alternative to diethyl azodicarboxylate (DEAD) or diisopropyl azodicarboxylate (DIAD) in Mitsunobu reaction.[9]
Ligated copper hydride.[10][11]
Heterogeneous catalysts: nickel-on-charcoal, copper-on-charcoal, nickel-in-graphite, copper+nickel-on-charcoal.

Methodologies

Higher-order organocuprates (Lipshutz cuprates).[12]
Chiral and achiral conjugate reductions.
Catalyst development for ppm Pd-catalyzed C-C couplings in water at ambient[13] [14]
Use of nonionic amphiphiles for transition metal-mediated cross coupling in organic synthesis.[15]
Low-cost synthesis of Coenzyme Q10.[16][17]

gollark: Heavpoot was able to work off fragmentary details of my design and the protocol specs, you know.

gollark: A *real* SPUDNET fan would reverse-engineer them.

gollark: I don't think you understand SPUDNET properly.

gollark: You probably don't have the keys.

gollark: I wasn't telling you to.
