Diphenylnitrilimine (2) adds regioselectively to 3-acylaminocoumarins (3a,b) and methyl α-acylamino-o-methoxycinnamate (4) to yield exclusively the cycloadducts (5a,b) and (8) respectively.Compounds 5 were converted into 8 by their treatment with KOH and

Diphenylnitrilimine 5 adds regioselectively to the carbon-carbon double bond of methyl β-aryl-N-benzoyl-α,β-didehydroalaninates 3 to afford the pyrazoline derivatives 6.The regiochemistry of the latter cycloadducts was evidenced chemically by their conver

The cycloaddition reactions of diphenylnitrilimine to coumarin, 3-ethoxycarbonyl and 3-acetylcoumarins were studied.The observed regiochemistry of the reaction with the coumarin 4a was the same as the one suggested by other researchers.For the coumarins 4
