A continuous-flow homogeneous photocatalytic method has been devised for the direct arylation of 2H-indazoles. This visible-light-promoted approach directly accesses a wide range of structurally diverse C3-arylated scaffolds of biological interest in a fast (1 min), single-step reaction by using eosin Y as an organophotocatalyst. Furthermore, a microreactor technology is also employed for the fast synthesis of liver X receptor inhibitor drugs with very good yields under metal-free conditions, whereas the reported methods required multiple steps and much longer reaction times (18-24 h).
