Synthetic applications of intramolecular aza-Wittig reaction for the preparation of heterocyclic compound
(Bentham Science Publishers, 2009)
[EN] A review focused on recent advances in intramolecular aza-Wittig reaction of phosphazenes with several carbonyl or analogous compounds is reported. Phosphazenes afford intramolecular aza-Wittig reaction with different ...
5-Ethoxy-1-(4-methoxyphenyl)-5-methyl-3-phenylimidazolidine-2,4-dione
(MDPI, 2021-05-28)
The title compound is a hydantoin derivative that has been synthesized through a three-component reaction of ethyl pyruvate, p-anisidine and phenyl isocyanate. This paper provides a comprehensive spectral dataset for the ...
Stereoselective inverse conjugate addition of nitrogen and carbon nucleophiles to allenyl phosphine oxide. Synthesis of α,β-unsaturated phosphine oxides
(ARKAT USA, Inc, 2012)
[EN] The reactivity of new three carbon synthon, generated in situ from the reaction of electrondeficient allenes with an appropriate phosphine as the catalyst, toward pronucleophilic reagents is described. Triphenylphos ...
Phosphorus substituted hydroxylamine and hydroxamic acid derivatives: synthesis and reactivity
(Arkat USA Inc, 2011)
[EN] This review summarizes several reports concerning the synthesis and synthetic applications of hydroxylamines derived from phosphines, phosphine oxides and phosphonates, and phosphorus substituted hydroxamic acid ...
Beta-Hydroxyimino Phosphorus Derivatives. An Efficient Tool in Organic Synthesis
(Bentham Science Publishers, 2011)
[EN] The purpose of this review article is to illustrate synthetic aspects of functionalized phosphorus derivatives containing an oximo moiety at the beta-position. First section will be focused on the synthesis of phosphine ...
Exploring the Synthetic Potential of γ-Lactam Derivatives Obtained from a Multicomponent Reaction—Applications as Antiproliferative Agents
(MDPI, 2022)
[EN] A study on the reactivity of 3-amino α,β-unsaturated γ-lactam derivatives obtained from a multicomponent reaction is presented. Key features of the substrates are the presence of an endocyclic α,β-unsaturated amide ...
Novel topoisomerase I inhibitors. Syntheses and biological evaluation of phosphorus substituted quinoline derivates with antiproliferative activity
(Elsevier, 2018-02-22)
This work describes the synthesis of 1,2,3,4-tetrahydroquinolinylphosphine oxides, phosphanes and phosphine sulfides as well as that of quinolinylphosphine oxides and phosphine sulfides, which were synthesized in good to ...
Antileishmanial Effect of 1,5- and 1,8-Substituted Fused Naphthyridines
(MDPI, 2023-12-22)
In the absence of a vaccine, there is a need to find new drugs for the treatment of neglected tropical diseases, such as leishmaniasis, that can overcome the many drawbacks of those currently used. These disadvantages ...
