Description

Methyl coumalate is a 2-pyrone and acts as dienophile in Diels-Alder reaction. It reacts with 1,3-butadienes at 100°C to yield tetrahydrocoumarins and 4-methoxycarbonyltricyclo[3.2.1.02,7]octenes. It also reacts with cyclohexadiene to afford tetrahydronaphthalene-2-carboxylate. It undergoes Diels-Alder reaction with unactivated alkenes to afford para-substituted adducts. It has been used as reagent in phosphine-catalyzed [4+3] annulation of modified allylic carbonates. It was also used in the preparation of 7-carboxyquinolizinium derivatives.
