A novel approach to the pyridoacridine ringsystem of the ascididemin‐type marine alkaloids is presented. This approach allows for the introduction of the ring A of the alkaloids by using a simple aromatic aldehyde building block. The viability of this approach is demonstrated with the synthesis of AK37, a bioactive deaza analogue of the alkaloid ascididemin. Starting from 3‐cyano‐4‐methylquinoline
