SE4:E8: From Discovery to Process, Part 2: Getting Ugi with it - scaling a 3CL protease inhibitor
Monday, 23 March, 2026

In Part 2 of our Pharm to Table deep dive on MK‑7845, Dani and LC shift from invention to implementation, welcoming process chemists Nastaran Salehi Marzijarani and Ben Turnbull to the pod. We explore how the team re‑imagined the synthesis to enable robust, scalable supply—and why a classic multicomponent reaction you probably remember from school, the Joullié–Ugi reaction, ended up stealing the show. Along the way, we unpack route selection trade‑offs, lifecycle thinking in process chemistry, and what it really takes to bring an antiviral to life at scale. Read and listen to some of the papers we discussed today:Asymmetric Synthesis of MK-7845, an Investigational Treatment for COVID-19 - Org.
