alternatives to side-chain protection and deprotection in solid-phase peptide synthesis (SPPS). Several protecting groups have been endorsed as suitable candidates, but finding a greener protecting group in SPPS has been challenging. Here, based on the 2-(o-nitrophenyl) propan-1-ol (Npp-OH) photolabile protecting group, a structural modification was carried out to synthesize a series of derivatives. Through experimental
近年来,人们做出了重大努力,以寻找更环保和安全的固相肽合成 (SPPS) 中侧链保护和去保护的替代方案。一些保护基已被认可为合适的候选者,但在 SPPS 中寻找更环保的保护基一直具有挑战性。在此,基于2-( o -nitrophenyl) propan-1-ol (Npp-OH) 光不稳定保护基团,进行结构修饰以合成一系列衍生物。通过实验验证,我们发现 3-( o-Nitrophenyl) butan-2-ol (Npb-OH) 具有较高的光释放率,对 Fmoc-SPPS(20% 哌啶 DMF 碱性溶液和纯 TFA 酸性溶液)的关键条件具有较高的耐受性,可作为脂肪族和芳香族羧基中的羧基保护基团。最后,Npb-OH成功应用于头尾环肽和侧链尾环肽的合成。此外,我们发现 Npb-OH 可以有效地抵抗二酮哌嗪 (DKP)。在光解速率验证过程中,与 3-( o -Nitrophenyl)but-3-en-2-ol
