The Cu(OTf)2 catalysed microwave assisted synthesis of a new scaffold, 7-aryl-7,8-dihydropyrido[4,3-c]pyridazin-5(6H)-one

Abstract:The synthesis of novel 7-aryl-7,8-dihydropyrido[4,3-c]pyridazin-5(6H)-ones is described including a one-step Mannich-type reaction followed by intramolecular ring closure of ethyl 3-methylpyridazine-4- carboxylate and aldimines, catalysed by the Lewis acid Cu(OTf)2 under microwave heating. This synthesis opens up possibilities to access this unexplored scaffold for medicinal chemistry.
