An efficient modification of the FukuyamaâMitsunobu procedure has been developed whereby primary or secondary amines can be synthesized from alkyl alcohols and the corresponding nosyl-protected/activated amine. Most importantly, the use of the DTBAD and diphenylpyridinylphosphine, as Mitsunobu reagents, generates reaction by-products that can be easily removed, providing a remarkably clean product mixture. This improved technique was implemented in the synthesis of a complex lipopeptide designed to target α9β1-integrin proteins predominant on upper airway epithelial cells.
已经开发出一种Fukuyama-Mitsunobu反应的高效改良方法,可以从烷基醇和相应的Nosyl保护/活化的胺合成伯胺或仲胺。最重要的是,作为Mitsunobu试剂的DTBAD和二苯并吡啶膦,生成的反应副产物易于去除,提供了极为纯净的产物混合物。这一改进技术已应用于合成一种复杂的脂肽,旨在靶向上呼吸道上皮细胞上丰富的α9β1整合素蛋白。
