Paragraph 0158-0160; 0162-0163, (2020/03/26)
PROBLEM TO BE SOLVED: To provide a synthesis method that allows high-yield continuous production of a compound of interest in synthesis and production of N-carboxyanhydride (NCA) and the like using a flow reactor. SOLUTION: In a synthesis method using a flow reactor 100, a basic solution adjusted in advance to a pH of 7-14 becomes acidic with a pH of 0-7, or an acidic solution adjusted in advance to a pH of 0-7 becomes basic with a pH of 7-14, within 60 seconds after the start of mixture of at least two ingredient solutions.

A novel multicomponent reaction of β-aminothiocarboxylic acids, aldehydes, and 3-dimethylamino-2-isocyanoacylate is described. During the course of this reaction two heterocyclic moieties, a thiazole and a β-lactam ring, are formed simultaneously and under mild conditions. The increase in molecular complexity here is dramatic as 2 C-N, 2 C-S and 1 C-C bonds are formed in a new 'one-pot' multicomponent reaction.
