antibacterial drug linezolid is synthesized from simple starting blocks by a convergent continuousflow sequence involving seven (7) chemical transformations. This is the highest total number of distinct reaction steps ever performed in continuousflow without conducting solvent exchanges or intermediate purification. Linezolid was obtained in 73 % isolated yield in a total residence time of 27 minutes
在此,重磅炸弹抗菌药物利奈唑胺由简单的起始嵌段通过涉及七(7)个化学转化的会聚连续流序列合成而成。这是有史以来在不进行溶剂交换或中间纯化的情况下连续进行的独特反应步骤的最高数量。在27分钟的总停留时间内,以73%的分离产率获得了利奈唑胺,对应于816 mg h -1的通量。

A new dinuclear chiral Co(salen) complexes bearing group 13 metals have been synthesized and characterized. The easily prepared complexes exhibited very high catalytic reactivity and enantioselectivity for the asymmetric ring opening of epoxides with H2O, chloride ions and carboxylic acids and consequently provide enantiomerically enriched terminalepoxides (>99% ee). It also catalyzes the asymmetric
