Abstract:This review discusses the synthetic pathways of an important class of quinolines known as pyrimido[4,5‐b]quinoline. Due to their profound range as biologically active compounds, they attracted the attention of medical/organic researchers. The construction of pyrimido[4,5‐b]quinolines involved the intermolecular cyclization of diamino chloropyrimidine carbaldehyde and intramolecular cyclization of 2‐amino‐3‐cyanotetra/hexahydroquinoline, 2‐aminoquinoline‐3‐carbonitriles, ester or amide. That class of organic co… Show more
