Abstract
A one-pot synthesis of 3-alkoxycarbonyl-3,4-dihydro-2H-pyran-2-ones from intermolecular hetero-Diels-Alder reaction between vinylidene Melderum's acids and dialkyl acetylenedicarboxylates, in the presence of simple alcohols at room temperature, is described. The advantages of this procedure are good yields, short reaction time, and easy workup. Antioxidant properties of four derivatives of these 3,4-dihydro-2H-pyran-2-ones, together with their antimicrobial activities, are investigated.

Rapid synthetic approaches to libraries of diversified 1,2-dihydrochromeno[2,3-c]pyrrole-3,9-diones and 3-(2-hydroxyphenyl)-4,5-dihydropyrrolo[3,4-c]pyrazol-6(1H)-ones. Mol Divers 2021; 26:1115-1128.

Abstract
An efficient and practical synthetic procedure for libraries of diversified 1,2-dihydrochromeno[2,3-c]pyrrole-3,9-diones using a multicomponent process is presented. A convenient synthetic procedure for obtaining functionalized 3-(2-hydroxyphenyl)-4,5-dihydropyrrolo[3,4-c]pyrazol-6(1H)-ones via ring-opening strategy has also been developed. This protocol was found to be compatible with a wide range of substituents and paves the way for the practical synthesis of title compounds with a broad range of substituents under mild condition. The products can be easily isolated by crystallization without the use of chromatography.
