process, and as a result, a synthetic procedure suitable for preparation of multihundred gram quantities of the final product, with 98% purity, has been developed. The new procedure does not require any purification by column chromatography for any of the reaction steps. The overall yield was increased from 5−8% in the medicinal chemistry route to 27% in the improved procedure.
Macrolones是一类新型的强效抗菌剂,它由大环内酯支架组成,喹诺酮单元通过各种连接子与大环内酯骨架束缚在一起,并与可乐定糖的4''- O-位置结合在一起。在本文中,描述了一种改进的由13步组成的系列化合物中铅化合物的路线。对药物化学路线中的关键反应步骤进行了修改,以进行最初的规模放大过程,结果,开发了适合制备数百克最终纯度为98%的最终产品的合成程序。对于任何反应步骤,新程序都不需要通过柱色谱法进行任何纯化。在改进的程序中,总收率从药物化学途径中的5-8%提高到27%。
