Abstract

Synthesis of the linear and angular furoquinolin‐4‐one derivatives 6 and 12 was performed, using nitrobenzofurans 3 and 9 as key intermediates. These compounds were reduced to the corresponding aminobenzofurans 4 and 10, which were condensed in two steps to yield, the linear furoquinolin‐4‐ones 6a,b and the angular ones 12a,b.
