acid NCA , which seemed to be the most universal method. Most of the obtained “β-sultam peptides” were sensitive against humidity, they hydrolyzed forming sulfonic acids, and reactions with amines resulted in sulfonamides. Reactions of N -acylated products showed that the sulfonyl group was faster attacked than the imide structure.
