1: Amphoteric compounds that have an acidic group and a basic group in their molecules are interesting compounds that exhibit the action of a base against acidic substances and the action of an acid against basic substances, but they lack physiological activity. At present, research on these substances has hardly progressed, except for various α-amino acids, amino acids, proteins, and taurine, which are attracting particular attention.

The structural features of the aminosulfonic acid compound represented by the above general formula are two basic nitrogen atoms present in the amorphous chain and a sulfonic group present at the terminal, and due to these, it exhibits extremely specific amphoteric properties. This is what is being done. However, for the purpose of having a basic group and an acidic group in the same molecule, the sulfone group may be a carboxyl group, and the hydrogen atom of the imino group can be used not only for an alkyl group but also for other groups. It does not matter if it is substituted with a substituent. From this point of view, the present inventors further developed the above invention and arrived at the present invention.

Multiplexing reaction of isocyanate compounds dissolved in a neutral solvent that does not release protons into the reaction system such as DMF, urethane bond formation reaction between isocyanate and a compound having active hydrogen, or isocyanate blocked with ketoxime etc. It has been found that when an amount of disabling solvent is present in the block dissociation reactions of compounds, the reaction rates of these reactions are increased and a catalytic effect is exhibited. The reaction catalytic action of the isocyanate group of aminosulfonic acid or carboxylic acid has not been known at all, and combined with the fact that the isocyanate group is soluble in organic solvents, it can be used for removal of protecting groups, polymerization, addition, and condensation reactions of compounds having isocyanate groups. We are looking forward to various developments in this area.
