Cascade Cyclization of <i>N</i>‑Cyanamide\nAlkenes for the Divergent Synthesis of Azido‑, Nitro‑,\nand Alkenyl-Containing Pyrroloquinazolinones

Radical cascade cyclizations of <i>N</i>-cyanamide alkenes\nhave been developed for the divergent synthesis of pyrroloquinazolinones\nbearing azido, alkenyl, and nitro groups by controlling the reaction\nconditions. The reaction temperature and the loading of the base play\nimportant roles in the different reaction pathways. These reactions\nare characterized by wide functional group compatibility and mild\nconditions.
