Phosphorylated azines are important structural motifs in a number of areas such as drug discovery, materials science and catalysis. Synthesis of stereo-defined chiral and selectively phosphorylated rings incorporating one or more nitrogen atoms is not a straightforward task. This issue has been addressed by a recent study reported by the group of Prof Jun-An Ma from Tianjin University (P. R. of China) who developed a novel strategy for accessing the title compounds.
Professor Ma said: “A novel class of phosphorylated tetrahydrotriazines, which would find use in drug discovery, were accessed via silver-catalyzed annulation based on readily available glycine imino esters and Seyferth–Gilbert reagent.”
