The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 5-Methylfuran-2(3H)-one( cas:591-12-8 ) is researched.Computed Properties of C5H6O2.Dell’Acqua, Andrea; Stadler, Bernhard M.; Kirchhecker, Sarah; Tin, Sergey; de Vries, Johannes G. published the article 《Scalable synthesis and polymerization of a β-angelica lactone derived monomer》 about this compound( cas:591-12-8 ) in Green Chemistry. Keywords: angelica lactone monomer ROMP film property. Let’s learn more about this compound (cas:591-12-8).

Bio-based levulinic acid is easily ring-closed to α-angelica lactone (α-AL). The α-AL can be isomerized to the conjugated β-AL under the influence of base, but since this is an equilibrium mixture it is very hard to devise a scalable process that would give pure β-AL. This problem was circumvented by distilling the equilibrium mixture to obtain a 90 : 10 mixture of β- and α-AL in 88% yield. This mixture was used for Diels-Alder reactions on 3 terpenes and on cyclopentadiene in up to 100 g scale. The latter DA adduct was subjected to a ROMP reaction catalyzed by the Grubbs II catalyst. The resulting polymer has some similarities to poly-norbornene but is more polar. The polymer can be processed into films with very good transparency.
