The Continuous-Flow Synthesis of Ibuprofen
Contributor(s):: Bogdan, Andrew R., Poe, Sarah L, Kubis, Daniel C., Broadwater, Steven J., McQuade, D. Tyler
Let relief flow forth! A three-step, continuous-flow synthesis of ibuprofen was accomplished using a simplified microreactor. By designing a synthesis in which excess reagents and byproducts are compatible with downstream reactions, no intermediate purification or isolation steps are required.
Continuous Synthesis of Carbamates from CO2 and Amines

We present a novel approach for the continuous preparation of carbamates. The simple yet fast synthetic route relies on directly utilizing carbon dioxide and, in contrast with the literature-known methods, only employs 1,8-diazabicyclo[5.4.0]undec-7-ene as an additive. The applicable amines’...
