A multistep continuous flow synthesis machine for the preparation of pyrazoles via a metal-free amine-redox process

Author affiliations

Abstract

A versatile multistep continuous flow setup is reported for the four-step conversion of anilines into pyrazole products. The synthesis machine incorporates the use of amine-redox chemistry through diazotization and a metal-free vitamin C mediated reduction. The machine can be used for the synthesis of an array of analogues or the scale up of an individual target.
