Abstract
Cycloaddition of diazomethane to pyrrolinones 1a,b,d,e affords only one regioisomer as a mixture of the epimeric pyrrolopyrazolines 2 and 2′,4‐Halo derivatives 1f,g react with diazomethane to give the two possible regioisomers 2 and 3. The regio‐ and stereochemistry of the adducts is evidenced by the 1H‐nmr data. The primary adducts originated from the halopyrrolinones suffer dehydrohalogenation to give aromatized products, which by further methylation give derivatives of type 7, 8, 10 and 11.
