Oseltamivir Phosphate

Herein the anti-influenza drug (–)-oseltamivir phosphate is prepared in continuous flow from ethyl shikimate with 54% overall yield over nine steps and total residence time of 3.5 min from the individual steps. Although the procedure involved intermediate isolation, the dangerous azide chemistry and intermediates involved were elegantly handled in situ. It is the first continuous-flow process for (–)-oseltamivir phosphate involving azide chemistry and (–)-shikimic acid as precursor.

Optimum Flow

In this paper, a micro-fluidic optimized process for the continuous flow synthesis of azo compounds is presented. The continuous flow synthesis of Sudan II azo dye was used as a model reaction for the study. At found optimal azo coupling reaction temperature and pH an investigation of the optimum flow rates of the reactants for the diazotization and azo coupling reactions in Little Things Factory-MS microreactors was performed. A conversion of 98% was achieved in approximately 2.4 minutes and a small library of azo compounds was thus generated under these reaction conditions from couplers with aminated or hydroxylated aromatic systems. The scaled up synthesis of these compounds in PTFE tubing (i.d. 1.5 mm) was also investigated, where good reaction conversions ranging between 66–91% were attained.
