ABSTRACT An Rh(III)-catalyzed synthesis of unsymmetrical acridines from aldehydes and azides through bilateral cyclization process in biomass-derived γ-valerolactone has been developed. The in situ-generated imino directing group (DG) from aldehyde and catalytic amount of BnNH2 worked as a transient directing group, thereby no additional steps were required for installation and removal of the DG.

A Rh(III)-catalyzed bilateral cyclization was developed for the efficient construction of acridines proceeding with C–H functionalization whereby in situ formation and removal of an imino transient directing group in the presence of catalytic amount of BnNH2 are achieved. In this transformation, a sequential Rh(III)-catalyzed C–H amination, cyclization, and aromatization process was involved.
