My first graduate school paper is officially out!! This one means the world to me. I’m proud to say it’s also an all-Latino authorship 🇲🇽. Grateful for the guidance, support, and the long coffee-fueled conversations with @R2G_UCSD that helped inspire this project. Stay tuned!

Our first foray into multicomponent aminosilylation where we show excellent reactivity and selectivity without additive base activators is out in #OrgLett. It even works on complex molecules with -COOH groups! Congrats @LeonelBJimenez! pubs.acs.org/doi/10.1021/acs…

Can we edit an amine after we’ve made it? In our new paper we show that C–N connectivity can be remodelled: disassemble a tertiary benzylamine & rebuild it with new structural information inserted. Great work from James, François, Kohl & Joe.@Gaunt_Group nature.com/articles/s41586-0…

Programmable remodelling of carbon–nitrogen connectivity in amines

Nature - Tertiary benzylamines can be transformed from static scaffolds into programmable platforms for molecular diversification through catalytic remodelling of their C–N bonds.

a lot of molecular innovation in covalent small molecules still neglects the covalent warhead itself. there’s a huge amount of chemical space left to optimize here. really nice work using strain-release bcbs as tunable acrylamide bioisosteres, with late-stage installation and no acrylamide polymerization problem. science.org/doi/10.1126/scie…

Late-stage functionalization with strain-release warheads enables tunable covalent inhibition

Is everyone as irritated as I am with the redesign of the ACS journal websites? The lack of TOC graphics on the ASAP pages for each article is ridiculous. This abysmal design needs to be reverted immediately. Everyone should send ACS an email and repost this far and wide!
