Abstract

5‐ and 8‐Nitroisoquinoline and some of their derivatives are aminated in a liquid ammonia solution of potassium permanganate to yield the corresponding 6‐ and 7‐amino compounds. From 5,7‐dinitroisoquinoline the 6,8‐diamino derivative is obtained; 1‐nitroisoquinoline has been found to be unreactive. FMO calculations made for a few nitroisoquinolines confirm the experimentally observed regioselectivity of the amination.
