Acid catalyzed monodehydro-2,5-diketopiperazine formation from N-α-ketoacyl amino acid amides
developed a new synthetic method for monodehydro-2,5-diketopiperazines (monodehydroDKPs), which is based on an acid catalyzed cyclization of N-α-ketoacyl aminoacidamides. Using this cyclization reaction, monodehydroDKP was formed with no or slight racemization in case that N-α-ketoacyl aminoacidamides with β-aliphatic-α-ketoacyl groups and sterically unhindered N-substituting groups at the C-terminal amide
