Our undergrad Rodrigo wondered if we could replace the bespoke chiral acid used in our recent asymmetric photochemistry with commercial (S)-TRIP. His protocol for enantioselective truxinate synthesis on 2-gram scale just dropped on @OrgSynth: https://t.co/Af1e9Yq2TS

Alana, Mihai, and Arindam reported a comprehensive synthetic, spectroscopic, and computational study on a general approach to alkene aziridination, now out in @ACSCatalysis! 🔺
pubs.acs.org
Aziridines are important targets for synthetic chemistry, and many methods involving the aziridination of alkenes by olefins with nitrenes have been reported. In general, however, nitrene transfer...

I’m very excited to share (a bit belatedly) this mechanistic story, published last week in @ScienceMagazine:
science.org
Stereochemical editing strategies have recently enabled the transformation of readily accessible substrates into rare and valuable products. Typically, site selectivity is achieved by minimizing...
