  Oxazoles are among the most important heterocyclic scaffolds in the fields of natural products and medicinal chemistry. Herein is developed a tandem reaction for the synthesis of a diverse array of 4,5-difunctionalized oxazoles utilizing easily-accessible ethyl 2-isocyanoacetate and aldehydes (26 examples, 31–83% yields). This cascade reaction is facilitated by catalytic CuBr and molecular oxygen as

  A multipurpose mesofluidic flow reactor capable of producing gram quantities of material has been developed as an automated synthesis platform for the rapid on-demand synthesis of key building blocks and small exploratory libraries. The reactor is configured to provide the maximum flexibility for screening of reaction parameters that incorporate on-chip mixing and columns of solid supported reagents to expedite the chemical syntheses.
