Abstract
Approximately 60% of small-molecule drugs contain nitrogen heterocycles in their molecular frameworks. Among the N-heterocycles, pyrrolo[2,1-a]isoquinolines and 2-pyrrolo[2,3-b]indoles stand out. Recently, our group reported a one-pot copper(II)-catalyzed conjugate addition/cyclization cascade method for the synthesis of phenylpyrrolo[1,2-a]isoquinolines. These compounds were evaluated ag…
