(S)-4-metilossazolidina-2,5-dione

Descrizione:

(S)-4-Methyl-2,5-oxazolidonedione is also known as N-Carboxy anhydrides. The Fuchs-Farthing method, reported in 1922, was the only practical method for preparing (S)-4-Methyl-2,5-oxazolidonedione[1]. N-Carboxy anhydrides (NCAs) are important as α-amino acid building blocks for the synthesis of oligopeptides and nonpeptide compounds, and for the synthesis of polypeptides[2]. The polymerization of NCAs is the main process for the preparation of polypeptides, and its purity and side chains can significantly affect the synthesized polypeptides. NCAs polymerizations have been initiated using many different nucleophiles and bases, the most common being primary amines and alkoxide anions[3].

(S)-4-Methyl-2,5-oxazolidinedione

CAS: 2224-52-4

(S)-4-Methyl-2,5-oxazolidinedione is a structural analog of the natural substrate for the enzyme, which is 4-methyl-2,5-diketopiperazine (MDP) and has been used as a model system to study the activation energy of ring opening. It reacts with trifluoroacetic acid to produce 2,5-oxazolidinedione and ammonium chloride. The reaction solution is then purified by extraction with a mixture of acetonitrile and hexane.
The product can be polymerized to form poly(2,5-oxazolidinedione), which can be used in the synthesis of polymers that have biorecognition elements. These polymers are characterized by their high stability and low reactivity.
