A concise, efficient and versatile synthesis of amino‐substituted benzo[b]pyrimido[5,4‐f]azepines: synthesis and spectroscopic characterization, together with the molecular and supramolecular structures of three products and one intermediate

A concise, efficient and versatile synthesis of amino‐substituted benzo[b]pyrimido[5,4‐f]azepines is described: starting from a 5‐allyl‐4,6‐dichloropyrimidine, the synthesis involves base‐catalysed aminolysis followed by intramolecular Friedel–Crafts cyclization. Four new amino‐substituted benzo[b]p...
