以化合物(CAS: 1629676-61-4)为原料合成9-氨基-4,7-二氧杂壬酸叔丁酯的一般步骤:向二苄胺27(35.0 g,85 mmol)的甲醇(420 mL)溶液中加入5% Pd/C(JM US 2.14 g),将混合物置于Atlantis反应器中,在40℃和15 psi的氢气压力下进行氢化反应。反应2小时后,通过过滤移除催化剂,浓缩滤液,得到18.90 g(产率96%)的胺7,为浑浊油状物,直接用于下一步反应无需进一步纯化。IR(ATR细胞):2977, 2868, 1727, 1456, 1393, 1367, 1254, 1157, 1113, 847, 755, 589, 564, 547, 536 cm^-1。^1H NMR(400 MHz, CDCl3):δ = 1.30(s, 9H), 2.36(t, J = 6.43 Hz, 2H), 2.71(t, J = 5.19 Hz, 2H), 3.36(t, J = 5.19 Hz, 2H), 3.43-3.50(m, 4H), 3.57(t, J = 6.64 Hz, 2H)。^13C NMR(100 MHz, CDCl3):δ = 28.18, 36.36, 41.92, 66.98, 70.32, 70.44, 73.58, 80.52, 170.92。HRMS(ESI):m/z [M + H]^+ C11H24NO4的计算值:234.16998;实测值:234.17009。

PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.
