Van advances to candidacy

Congrats to super second-year grad student Van Tran, who passed her qual exam with flying colors! Van is the first member of the second class of grad students in the Engle lab to advance to candidacy. Way to go, Van!

New Review on Conjunctive Cross-Coupling

Congrats to Joe, Van, and Vincent for publication of their invited review on conjunctive cross-coupling which appears online today in Aldrichimica Acta! The review focuses on advances in the use of carbon–carbon π-bonds as conjuctive reagents, or synthetic lynchpins, to merge two conventional reactive fragments under transition metal catalysis.

Directed 1,2-Dialkylation of Alkenes – Now In Press

Our paper describing directed 1,2-dialkylation of alkenyl carbonyl compounds via nickel catalysis is now online in Chem. Sci. This work represents the first method for controlled introduction of differentiated alkyl groups onto an non-conjugated alkene and offers exciting potential for generating densely functionalized products with high-sp3 content in a rapid manner. Congrats to the authors, Joe, Vincent, Van, and Mingyu! Special shout out to undergraduate co-author and TSRI-SURF program alum Vincent. Click here for a link to the paper. A pre-print of this work was published on ChemRxiv back in January (click here).

Gamma-Selective Alkene Hydroarylation with Arylboronic Acids

As part of an ongoing collaboration with Pfizer, today we report a new method for achieving γ-selective hydroarylation of alkenyl carbonyl compounds, which is available as a pre-print on ChemRxiv (click here).  This reaction is notable for its simplicity, practicality, and functional group tolerance. Because of the ubiquity of arylboronic acids in pharma and in academia, this protocol offers a powerful approach to appending an aryl group of one’s choosing to the γ-position of a carboxylic acid substrate. Congrats to all of the authors: Rei, Tanner, Kin, and Rohan from TSRI; and Gary, Shouliang, Mingying, Fen, and Indra from Pfizer. It was great working with the Pfizer team to field-test the method and to identify valuable heterarylboronic acids that would be of interest to medicinal chemists. Special shoutout to high school student co-author, Rohan, who worked with us earlier this year as part of his junior year internship. Great work, team! Stay tuned for the peer-reviewed version.

Catalytic 1,3-Diene Synthesis via C(alkenyl)–H Activation

In an Article appearing online today in J. Am. Chem. Soc., the Engle lab and Liu lab (U Pittsburgh) report a detailed study of palladium(II)-catalyzed C(alkenyl)–H activation, including optimization of a method to prepare structurally diverse 1,3-dienes, organometallic synthesis of key intermediates relevant to catalysis, and experimental/computational studies to interrogate the reaction mechanism. Congrats to the whole team: Mingyu, Pusu, and Malkanthi from Scripps; and Yanyan from Pitt. Special shout out to undergraduate co-author Pusu, who was a visiting student from Nankai university for six months. Thanks to the Liu lab for another fruitful collaboration! Way to go, everyone!
