Copper-Catalyzed [3 + 2] Cycloaddition Reaction of <i>N</i>-Hydroxysuccinimide Ester with Isocyanoacetates for the Synthesis of 4,5-Disubstituted Oxazoles
The cycloaddition reaction of N-hydroxysuccinimide ester and isocyanatoacetate catalyzed by copper was described. A series of 4,5-disubstituted oxazole compounds, including ones derived from natural fatty acids, drugs, amino acids, and peptides, were obtained in moderate to high yields. The derivatization reaction was explored. The reaction mechanism was discussed.

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.
