Syntheses of methyl 2-bromo- and 2-iodo-2,3-butadienoates 3 and 6 from readily available starting materials are described. 3 and 6 will be valuable building blocks for the synthesis of 2-aryl and 2-alkenyl substituted alka- 2,3-dienoates via Palladium-cat

A versatile synthetic method for preparing 3-pyrazolin-5-ones and 5,8-dihydro-1H-pyrazolo[1,2-a]pyridazines from simple β-keto esters is demonstrated. The synthetic strategies involve the acylation of β-keto esters, cyclocondensation with hydrazine followed by trapping with a diene under oxidative conditions.
