Pd-catalyzed chemoselective Catellani ortho-arylation of iodopyrroles: rapid total synthesis of rhazinal.

ABSTRACT

A Pd-catalyzed chemoselective Catellani reaction of iodopyrroles was developed. The rare chemoselectivity between two different aryl halides was realized by optimizing the kinetics of the different steps of this multicomponent process. The new developed method led to the rapid synthesis of rhazinal in a highly efficient manner.
