An efficient microwave-assisted synthesis and biological properties of polysubstituted pyrimidinyl- and 1,3,5-triazinylphosphonic acids
摘要:
Polysubstituted pyrimidinylphosphonic and 1,3,5-triazinylphosphonic acids with potential biological properties were prepared in high yields by the microwave-assisted Michaelis Arbuzov reaction of trialkyl phosphite with the corresponding halopyrimidines and halo-1,3,5-triazines, respectively, followed by the standard deprotection of the phosphonate group using TMSBr in acetonitrile. 4,6-Diamino-5chloropyrimidin-2-ylphosphonic acid (7a) was found to exhibit a weak to moderate anti-influenza activity (28-50 uM) and may represent a novel hit for further SAR studies and antiviral improvement.

[EN] Triazine compounds useful as flame retardants have the formula (I) where Am represents an amino group, Pp represents a phosphonic group and Z represents an amino group or a phosphonic group, or are polymers comprising repeating units of formula (II), where (a) is a diamine residue. The triazine compounds are used as flame retardants in plastic materials, particularly polyurethane foam or artificial fibres, or in intumescent fire protection compositions. [FR] Les composés de triazine utilisés comme retardateurs de flamme répondent à la formule (I) où Am représente un groupe amino, Pp représente un groupe phosphonique et Z représente un groupe amino ou un groupe phosphonique, ou sont des polymères contenant des motifs répétitifs répondant à la formule (II) où (a) est un reste diamine. Les composés de triazine sont utilisés comme retardateurs de flamme dans les matières plastiques, en particulier la mousse de polyuréthane ou les fibres artificielles, on encore dans des compositions intumescentes de protection contre les incendies.
