Sustainable Manufacturing Process for Commercial and Developmental Stage Intermediates through Two Consecutive Flow Reactions using Micro-packed Bed Technology

2024 CMO Excellence in Green Chemistry Award

The PharmaBlock team was selected based on their innovative work on “Sustainable Manufacturing Process for Commercial and Developmental Stage Intermediates through Two Consecutive Flow Reactions using Micro-Packed Bed Technology.” Team members are Feng Zhang, Guangchao Ma, Dafen Wen, Yang Zhu, and Yuanxian Wang, all based in Nanjing, China. Their project demonstrated the use of micro-packed bed technology to produce tert-Butyl 3-oxoazetidine-1-carboxylate and tert-Butyl 3-aminoazetidine-1-carboxylate through oxidation reactions and reductive amination reactions at scale, resulting in improvements to safety, equipment volume efficiency, process mass intensity (PMI), greenness, and cost efficiency.
