Abstract
Rapid dual activation (≤3.3 s) of both β-amino acid N-carboxy anhydride and alkyl chloroformate for the synthesis of a β-amino acid-derived scaffold was demonstrated. The key to success was the use of rapid mixing enabled by using a micro-flow reactor. The one-flow synthesis of 22 β-amino acid derivatives was achieved.
