[EN] PROCESS FOR THE PREPARATION OF CYCLOPROPYLDIKETOPIPERAZINES AND OF A KEY INTERMEDIATE OF DS-5272 [FR] PROCÉDÉ DE PRÉPARATION DE CYCLOPROPYLDICÉTOPIPÉRAZINES ET D'UN INTERMÉDIAIRE CLÉ DE DS-5272
development is often limited by their challenging preparation. In this work, we present a simple route to cyclic poly(α-peptoids) from N-alkylated-N-carboxyanhydrides (NNCA) using LiHMDS promoted ring-expansion polymerization (REP) in DMF. This new method allows the unprecedented use of lysine-like monomers in REP to design bioactive macrocycles bearing pharmaceutical potential against Clostridioides

versatile N-carboxyanhydrides (NCAs) directly from amino acids and CO2 using n-propylphosphonic anhydride. Most of the NCAs were isolated with >95% purity after simple workup, avoiding the need for tedious purification procedures typically required using conventional methods. Because the reagents and conditions employed are mild, tandem reactions with moisture-sensitive NCAs were carried out to transform
