Abstract
A new and convergent synthesis of azaphenanthridines via an anionic ring closure is reported. Ortho-lithiation/in situ borylation of cyanopyridines produces the corresponding cyanopyridylboronic esters, which undergo a Suzuki–Miyaura cross-coupling to give the key intermediates. Addition of lithium morpholide produces the azaphenanthridines.
