The final, peer-reviewed version of our study describing a new method to form cyclopropanes from unactivated olefins and 1,3-dicarbonyl compounds under Pd(II)/Pd(IV) catalysis is online this week in J. Am. Chem. Soc. Owing to its unique mechanism, the method gives an unusual stereochemical outcome in which the 1,3-dicarbonyl adds to opposite faces of the C–C π-bond. Congrats to the team of collaborators from Scripps Research, University of Pittsburgh, Purdue University, and Pfizer!
