An improved general method for automated synthesis of tripeptides was developed, in which methanesulfonic acid (MSA) was used in place of trifluoroacetic acid (TFA), thus making it possible to avoid, 1) corrosion of the apparatus by strong acid vapor, 2) formation of emulsions, and 3) use of the restricted solvent, dichloromethane. As an application of the automated synthesis apparatus, 216 fragment tripeptide derivatives were synthesized systematically using the MSA method, in excellent yield and with increased efficiency.
开发了一种改进的用于三肽自动化合成的一般方法,在该方法中使用甲磺酸(MSA)代替三氟乙酸(TFA),从而避免了以下问题:1)强酸蒸汽对设备的腐蚀,2)乳液的形成,以及3)使用受限的溶剂二氯甲烷。作为自动化合成设备的应用,使用MSA方法系统地合成了216种片段三肽衍生物,产量极高,效率提高。
