摘要:
使用乙酸酐对截短侧耳素11’-羟基进行保护,水解掉2-羟基乙酸,与2-巯基乙酸酯化,再与2-二乙氨基乙醇氨化,得到泰妙菌素。工艺中以2-二乙氨基乙醇代替2-二乙胺基乙硫醇作为侧链底物合成延胡索酸泰妙菌素,降低了有毒有害反应物对工业合成路线带来的额外成本。最终质量分数可达到920~960 mg/g。

Abstract:
Use 2-(diethylamino)ethanol instead of 2-(diethylamino)ethanethiol, as side-chain radical to synthesize tiamulin fumarate,In order to reduce the risk and the additional costs of that use the toxic chemicals. The protection against 11’hydroxyl of pleuromutilins is acetic anhydride,hydrolysis and removal 2-hydroxyacetic acid of pleuromutilins,esterify with 2-mercaptoacetic acid and aminate with 2-(diethylamino)ethanol to Synthesis tiamulin fumarate. In the conclusion,the content of tiamulin fumarate is 920~960 mg/g,and the the yield of amount of substance is 87.7%.
Key words:  pleuromulin  tiamulin fumarate  2-(diethylamino)ethanethiol  2-(diethylamino)ethanol
