Diels-Alder reactions of 2-methylpyridazin-3(2H)-ones, substituted with ethylsulphonyl, cyano and methoxycarbonyl groups at the 4- or 5-positions, with 1,3-dienes have been investigated. Pyridazinones behave as poor dienophiles and their reactivity depends on the nature and position of the substituents. 5-Substituted pyridazinones are more reactive than the 4-substituted isomers and high conversions
