Are you #team_abstraction or #team_substitution to break C-Cl bonds? Check out work by Samir, Imma, and Blaise in @angew_chem on an electrocatalytic system that can switch between these mechanisms to functionalize unactivated chloroalkanes. tinyurl.com/mr4yf55y

This ride isn’t over yet but its hard not to look back on all I’ve learned about the great games of synthesis and medchem since I started a career as a young BS chemist. Thank you for your support & friendship and looking fwd to many more years (& maybe a drug to market...)

A wonderful paper out now in @OPRD_ACS from the #PfizerChemistry team detailing the work that went into Lufotrelvir which was under development alongside Nirmatrelvir/Paxlovid - just amazing work done on compressed timelines during lockdowns
