Title:
α-CARBONYL ALKENYL ESTER COMPOUND, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/169199
Kind Code:
A1
Abstract:
Provided are an α-carbonyl alkenyl ester compound and a preparation method therefor, and said compound is further used to react with a primary or secondary amine to prepare an amide compound. Said two reactions are combined to develop an amide bond and peptide bond formation method that use carboxylic acid and amine as starting materials and allenyl ketone as a condensing agent. The α-carbonyl alkenyl ester compound of an α-amino acid serves as a peptide synthesis building block and is used in peptide solid phase synthesis. The method has mild reaction conditions, is simple to operate, and has a high yield. Compared with existing amide bond condensation reagents, allenyl ketone has the advantages of being simple to prepare, having good stability, a low molecular weight, not racemizing when activating α-chiral carboxylic acid, and so on, and is a novel amide bond and peptide bond condensing agent.
