A transition metal-free tandem process to pyridazinopyrido[3,2-f][1,4]thiazepine-diones via Smiles rearrangement

Abstract

A transition metal-free methodology for the synthesis of pyridazinopyrido[3,2-f][1,4]thiazepine-diones was studied. The construction of this tricyclic system went through a one-pot coupling/Smiles rearrangement/cyclization process. The high yields of pure products were obtained through simple recrystallization.
