phenolic ester mediated peptide synthesis is an efficient and well established method, the same via totally unsubstituted phenyl ester is not preferred due to the extremely slow rate of aminolysis. We have investigated the scope of the unsubstituted phenyl ester as an intermediate in peptide bond formation and found that it may be useful for the design of chemoselective peptide ligation when HOBt is used
尽管取代酚酸酯介导的肽合成是一种有效且完善的方法,但由于氨解的速度极慢,因此通过完全未取代的苯基酯进行的合成不是优选的。我们研究了未取代的苯基酯作为肽键形成中间体的范围,发现当HOBt用作酰基转移催化剂时,它可用于化学选择性肽连接的设计。探索了HOBt催化的,含氧酯介导的连接的范围,以合成在连接肽N端含有半胱氨酸,丝氨酸和苏氨酸的寡肽。
