Synthesis of novel thiol taxoids based on the 7,10-di-(2,2,2-trichloroethyloxycarbonyl)-10-deacetylbaccatin III: both the syn and anti 10-deacetyl-2′-deoxy-2′-mercaptopaclitaxels

Two new kinds of docetaxel compound, with a mercapto group instead of the hydroxyl on the C13 side chain (both syn and anti), via the 7,10-di-(2,2,2-trichloroethyloxycarbonyl)-10-deacetylbaccatin III route, were synthesized. The uses of trans and cis oxazoline compounds, and their stereoselective ring-opening reactions with thiolacetic acid, were proved to be key steps.
两种新的多西他赛化合物,通过7,10-二-(2,2,2-三氯乙氧羰基)-10-去乙酰基浆果赤霉素III途径,具有巯基而不是C13侧链上的羟基(顺式和反式) ,被合成。的使用反式和顺式恶唑啉化合物,并用硫羟乙酸及其立体选择性开环反应,被证明是关键步骤。
