Quartz glass - micro photo the reactor and the synthesis of 10 - hydroxy camptothecin and 7 - alkyl - 10 - hydroxy camptothecin

摘要

The present invention relates to a process for the preparation of 10 - hydroxy camptothecin, as well as of 7 - alkyl - 10 - hydroxy camptothecin, comprising the steps ofA provision of a continuous fluid flow with thickness d of a solution of camptothecin - n - oxide or 7 - alkyl - camptothecin - n - oxide,B passing the current to at least one light source which emits light parallel to the thickness d, d in the case of 10 μm to 1000 μm.and devices for carrying out the method.
