Recent advances in the synthesis of chromenone fused pyrrolo[2,1- a ]isoquinoline derivatives

This review, from 2016 to 2022, summarizes advances in the synthesis of 2- and 4-chromenones fused to the five-membered ring of pyrrolo[2,1- a ]isoquinolines in diverse orientations highlighting modes of ring construction by classical and transition metal-catalyzed methods.
