Antimicrobial activity of new 4,6-disubstituted pyrimidine, pyrazoline, and pyran derivatives.
TL;DR: A number of new 2,6-didisubstituted pyrimidine, pyrazoline, and pyran derivatives were synthesized starting from their chalcone derivative and displayed different degrees of antimicrobial activity against Bscillus subtilis, Pseudomonas aeruginosa, and Streptomyces species.
Journal ArticleDOI
Triacetic acid lactone as a bioprivileged molecule in organic synthesis
TL;DR: The triacetic acid lactone belongs to both pyrones and polyketides, which provides opportunities for its obtaining by chemical and biological methods as mentioned in this paper, as well as its ability of undergoing transformations with both preservation and opening of the ring, ensure its multiple reactivity.
Journal ArticleDOI
Synthesis of Multifunctionalized 2,3-Dihydro-4-pyridones and 4-Pyridones via the Reaction of Carbamoylated Enaminones with Aldehydes.
TL;DR: The novel and effective diastereoselective synthesis of multifunctionalized dihydropyridones, including CF3-substituted derivatives, has been developed on the basis of the piperidine-promoted domino reaction of carbamoylated enaminones with aldehydes.
Journal ArticleDOI
Bio-based triacetic acid lactone in the synthesis of azaheterocycles via a ring-opening transformation
TL;DR: In this paper, a new way of converting bio-based triacetic acid lactone (TAL) into azaheterocyclic compounds, such as 4-pyridones, pyrazoles, isoxazolines and isoxoxazoles, has been found.
