Big news out of the Johnson group this week: our most recent publication is now in @ScienceMagazine ! science.org/doi/10.1126/scie… 1/

Doubly stereoconvergent crystallization enabled by asymmetric catalysis

Chiral base catalysis paired with product crystallization can set three adjacent stereocenters in a Michael addition.

Congratulations to Susanna Angles on her first lead-author paper! If you're feeling salty, check out how she and Amgen Scholar Alannah Miller access enantiopure halogenated carboxylic acids through dynamic crystallizations of diastereomeric salt pairs. pubs.acs.org/doi/10.1021/acs…

Synchronicity isn't just for Sting - it’s for aromaticity too! Out now, a [3 2]-dipolar cycloaddition is followed by a Claisen rearrangement driven by synchronized aromaticity, affording novel 2,4-cyclohexadienones. Congrats, Will, Michael, and Shubin! pubs.acs.org/doi/10.1021/acs…

Letting today go by without wishing you a happy Halloween would be despicable! So Happy Halloween from the Johnson Group Minions 🎃

Congrats, Will, Dorian Vallantin, Tabea Nett and the Darses Group! The crew found benzofurans and indoles could undergo cyclopropanation with a Cu(II) catalyst, providing a sustainable alternative to traditional Rh(II)-catalyzed Buchner cyclopropanations. pubs.acs.org/doi/full/10.102…
