At first, HEBP was synthesized. HBP (1.9 g), K2CO3 (2.76 g), and 2-bromoethanol (1.25 g) were mixed, and the reaction was proceeded for 24 h at 110 °C. The resultant was extracted with dichloromethane and then purified by silica gel column chromatography to provide HEBP as a white crystalline solid.Then HEBP (484 mg), zinc powder (160 mg), THF (3 mL), and TiCl4 (0.5 mL) were mixed under nitrogen atmosphere. The reaction was carried out under stirring for 12 h and then quenched by the addition of hydrochloric acid. The resultant was extracted with ethyl acetate and dried over anhydrous Na2SO4. The crude product was purified by silica gel column chromatography. HO-TPE-OH was isolated as a yellow solid.

HO-TPE-OH的分解成HO-TPE-OH的备制步骤如前上述[38]。前提,结合了HEBP。将HBP(1.9 g)、K2CO3(2.76 g)和2-溴无水乙醇(1.25 g)混后,在110°C下想法24H。获取物用二氯丁烷提纯,再能够矽胶柱色谱纯化,获取小白结晶体混合物HEBP。最后在N2紧张感下混杂HEBP(484mg)、锌粉(160mg)、THF(3mL)和TiCl4(0.5mL)。反映在混和下完成12分钟,最后确认倒入硝酸淬灭。所得额物用乙酸乙酯浸提,用无水Na2SO4干燥处理。粗物品确认矽胶柱色谱纯化。HO-TPE-OH分离出来为米黄色粉末状。关于分享:Palmitic acid-PEG-COOHPalmitic acid-PEG-MalPalmitic acid-PEG-NH2Palmitic acid-PEG-SCRB-PEG-DSPESTA-PEG-CHOSTA-PEG-COOHSTA-PEG-FASTA-PEG-FITCSTA-PEG-MalSTA-PEG-NBDSTA-PEG-NH2STA-PEG-OHSTA-PEG-SCSTA-PEG-SH往上软文项目源头当下杂志或论文资料,告之商标侵权请结合他们移除!
