The acid density of TFA functionalised Zr–TMS (Zr–TMS–TFA) materials increased with loading of TFA from 5 through 25wt.%. The catalytic performance of Zr–TMS–TFA catalysts was evaluated in Michael addition of 3-methylindole to α,β-unsaturated ketones under liquid phase and solvent free...
TMSTS/TFA/DMS对保护肽树脂的酸解 来自 知网 喜欢 0 阅读量: 108 作者:王德心,Tam,TP 摘要: 以三氟甲磺酸三甲基硅醇酯/三氟醋酸/二甲基硫醚作酸解试剂,对几种常见的氨基酸侧链保护基如 Bzl、For 及 Pme 等的脱除进行了最优条件的摸索,并已用于两个十二肽的制备。分步裂解的总收率可达85%以上。
