Herein, we present the synthesis of N-(3-methoxyphenethyl)-2-propylpentanamide, a derivative of valproic acid. The compound has been thoroughly characterized through melting-point determination, 1H and 13C NMR spectroscopy, infrared spectroscopy, and...

Benzyl 2,4-dichlorophenyl sulfoxide was synthesized both in racemic and in an enantiopure form. This enantiopure sulfoxide is a further successful confirmation of our straightforward protocol to yield easily chiral aryl benzyl sulfoxides. We solved a...

In 2019, carbamates derived from 3-hydroxypyridine were classified as nerve agents and subsequently included in the Annex on Chemicals by the Conference of the States Parties. Herein, we describe the preparation of a structural simulant of this class...

Perimidine derivatives are versatile heterocycles with growing significance in medicinal chemistry and materials sciences. However, their structural variety remains limited. This study focused on the synthesis and crystal structure characterization o...

Friedelin, a pentacyclic triterpene, has been reported to inhibit potential reactive oxygen species (ROS)-scavenging activity. Accordingly, we modified the structure of this compound with the aim of obtaining derivatives. A new derivative (compound 4...

We report the first synthesis of 3,5-diamino-substituted dithieno[3,2-b:2′,3′-d]thiophene derivatives, bearing alkoxycarbonyl or acetyl groups at C-2 and C-6 positions. The target compounds were prepared via the reaction of 3,4-dibromothi...

(S)-2-methyl-5-(prop-1-en-2-yl)cyclopent-1-ene-1-carbaldehyde (2) is a component of the essential oils of several plants and has also been used in many syntheses, usually of terpenes. Although the preparation of compound 2 has been reported several t...

1β, 6α-dihydroxy-5αH-eudesma-3(4), 11(13)-dien-12, 8β-olide is a natural eudesmane sesquiterpene lactone isolated from the aerial parts of Inula nervosa Wall. In this paper, we report the X-ray crystallography of the compound 1...

The multicomponent synthesis of a novel and highly symmetric polyheterocycle based on the pyrrolo[3,4-b]pyridin-5-one core incorporating the privileged tetrahydroisoquinoline moiety is described. The target compound was synthesized as an inseparable...

Compounds based on the pyrazoloquinazoline scaffold are of significant interest in synthetic organic chemistry owing to their potential biological activity. In this work, we describe the synthesis of a new derivative with this scaffold, 9-oxo-2-(p-to...
