Abstract Peptide chloromethyl esters are important compounds in prodrug synthesis. A simple, mild and efficient method for the synthesis of chloromethyl esters of N-blocked amino acids and dipeptides using exclusively bromochloromethane is reported. These N-blocked amino acid and dipeptide chloromethyl esters react readily with the carboxylic acid group of aspirin and with the sulfonamido group of
摘要 肽氯甲酯是前药合成中的重要化合物。报道了一种仅使用溴氯甲烷合成 N 封闭氨基酸和二肽的氯甲酯的简单、温和且有效的方法。这些 N 封闭的氨基酸和二肽氯甲酯很容易与阿司匹林的羧酸基团和抗疟药磺胺二甲嘧啶的磺胺基反应,得到相应的前药。

solid-supported peptide. This photochemical methodology could be used iteratively, but it lacked efficiency. The procedure was most effective for segment condensation peptidesynthesis. A tripeptide fragment containing two nonproteinogenic aminoacids was synthesis by chromiumcarbenecomplexphotochemistry. This tripeptide was incorporated into a merrifield resin supported tripeptide, deprotected,
