One substrate, two outcomes.
By switching the Lewis base catalyst, we can selectively access either branched or linear homoallylic tertiary fluorides with high stereocontrol. Mechanistic studies reveal how two closely related onium species lead to divergent reaction pathways.
Now published in ACS Catalysis! Congrats to the team :)

It’s been a while since we posted here!
Turns out our cyclopropenimine–thiourea catalysts don’t just work for small molecules, they can work for polymers too :) In a collaboration with Prof. Byeong-Su Kim's group, we applied our catalyst platform to the stereoselective polymerization of rac-lactide. Happy to share the story @angew_chem

Aside from being a really nice advance in Bronsted base organocatalysis, this paper has a really exceptionally well-organized SI, particularly with regard to substrate preparation! Check it out!

A Goldberg machine meets asymmetric synthesis! The cover shows a whimsical take on stereodivergent α-azaaryl carbonyl reactions using dual chiral catalysts (Cu + Ir/Pd/Ni/Ru/amines) to access all stereoisomers. Prof. Sarah Yunmi Lee at KAIST
