Base-promoted ring-opening/recyclization of naphthoquinones to access benzo[5,6][1,4]thiazino[4,3- b ]isoquinoline-7,12-diones at room temperature

This is the authors' abstract. We don't add key points for this paper.

A novel and unique nitrogen atom insertion into naphthoquinone rings to construct structurally valuable polycyclic heterocycles at room temperature under transition-metal-free conditions has been described.
