Five-Membered 2,3-Dioxoheterocycles: LXXXIV.[4+2]-Cydoaddition of Styrene to 4,5-Diaroyl-1H-pyrrole-2,3-diones. Crystal and Molecular Structures of 7a-(2,5-DimethylbeEzoyl)-4-(2,5-dimethylphenyl)-1-(4-methoxyphenyl)-6-phenyl-7,7a-dihydropyrano [4,3-b)-pyrrole-253(1H,6H)-dione

摘要

1-Aryl-4,5-diaroyl-1H-pyrrole-2,3-diones react with styrene to form substituted 7,7a-dihydropyrano[4,3-b] pyrrole-2,3(1H,6H)-diones whose structure was confirmed by XRD analysis. The crystal and molecular structure of 7a-{2,5-dimethylbenzoyl)-4-(2,5-dimethyl-phenyl)-1-(4-methoxyphenyl)-6-phenyl-7,7a-dihydropyrano[4,3-b] pyrrole-2,3(1H,6H)dione was examined.
