The formation of Csp3–Csp2 bonds is a powerful means of synthesizing high-value chemicals. Nickel catalysis has offered numerous avenues to Csp3–Csp2 bond assembly via cross coupling of Csp3 electrophiles, but…
The translation of olefin metathesis reactions from the laboratory to process scale has, historically, been challenging with traditional batch techniques due to mass-transport limitations that negatively influence the efficiency of…
Complex [(DMPU)2Zn(CF2H)2] 1 is a crystalline organometallic reagent with utility in various catalytic difluoromethylation reactions under mild conditions. Unfortunately, this reagent isn’t commercially available, and the procedure for the preparation…
This article shares our process for developing an improved API synthesis of raltegravir. Through this process, the team isolated a new process intermediate and develop conditions to solve the selectivity…
In this article, we discuss how our team at Snapdragon Chemistry, in collaboration with Qpex Biopharma, Inc., designed and built a convenient development-scale reactor (0.44 mol/h) to prepare diazomethane from…
Leveraging a High-Temperature Thermal Racemization to Recycle the Classical Resolution Waste Stream In part one of this two-part series, “Development of a Classical Resolution to Prepare an Atropisomerically Pure Sotorasib…
In this article, we describe our work with Amgen on the process development efforts to improve the final methylation step in the AMG 397 drug substance process, culminating in the…
In our recent article, our team in Milan explains how they developed an improved synthesis of the active pharmaceutical ingredient (API) dimethyl fumarate. Previously, commercial production strategies of dimethyl fumarate…
The ketone intermediate, LSN647712, is a key synthetic intermediate for Eli Lilly’s drug substance lasmiditan during its manufacturing process. In this article, we explain how our team at Snapdragon Chemistry…
In a recent article in Chemistry Today, Snapdragon Chemistry’s David Ford discusses how AI and data science may fundamentally change how we approach process development and early deliveries of active…
