A convenient and efficient palladium-catalysed retro-ene-assisted method has been developed to prepare a series of 5-substituted-6-phenyl-3(2H)- pyridazinones as potential antiplatelet drugs. The most active compounds were those that contain a 3-phenyl-3-

A new method for the traceless solid phase synthesis of 3(2H)-pyridazinones has been developed employing dihydropyran-functionalized resin. The procedure has permitted the preparation of several diarylpyridazinones through a Suzuki cross-coupling reaction and cleavage conditions that promoted a retro-ene fragmentation.
Pyridazines. Part 30:1 Palladium-catalysed synthesis of 5-substituted 6-phenyl-3(2H)-pyridazinones asissted by a retro-ene transformation

The efficient one-pot functionalization, through palladium-catalysed reactions, of position 5 of the 6-phenyl-3(2H)-pyridazinone system has been performed using a retro-ene-assisted fragmentation. This route allows access through a short synthetic sequenc
