Syntheses and Reactions of s-Triazine Derivatives

Nitrogen-14 NQR in s-Triazine Derivatives*

Within a study of the temperature dependence of NQR frequencies in some s-triazine derivatives [1], resonance frequencies at 4.2 K were determined in melamine, cyanuric acid, and cyanuric chloride. New lines, which were not reported so far, were detected in two of these compounds. In melamine, nine more lines were found as already described in [4], In cyanuric chloride, two more lines were foun...

Organocatalytic asymmetric assembly reactions for the syntheses of carbohydrate derivatives by intermolecular Michael-Henry reactions.

Given the significance of carbohydrates in life, medicine, and industry, the development of simple and efficient de novo methods to synthesize carbohydrates are highly desirable. Organocatalytic asymmetric assembly reactions are powerful tools to rapidly construct molecules with stereochemical complexity from simple precursors. Here, we present a simple and robust methodology for the asymmetric...

Oxidative Degradation Of Triazine Derivatives

Syntheses of Anisomycin Derivatives

The structure of anisomycin has been determined by X-ray investigation4 and the absolute configuration was confirmed by chemical correlation.5 Anisomycin has attracted considerable synthetic interest, and several synthetic studies, derivative syntheses as well as total syntheses, have been reported.6 Especially, the synthesis of its analogues has revealed the structure-activity relationship of ...

Design, synthesis and biological evaluation of antimalarial activity of new derivatives of 2,4,6-s-triazine

Dihydrofolate reductase (DHFR) is an important enzyme for de novo synthesis of nucleotides in Plasmodium falciparum and it is essential for cell proliferation. DHFR is a well known antimalarial target for drugs like cycloguanil and pyrimethamine which target its inhibition for their pharmacological actions. However, the clinical efficacies of these antimalarial drugs have been compromising due ...
