Acyclic to cyclic aminophosphonic and phosphinic acids
The results presented in this account deal with the synthesis of acyclic αor β-aminophosphonates or phosphinates and with the synthesis of heterocyclic compounds, where the phosphorus and/or the nitrogen atoms can be embedded in the heterocyclic core, showing new perspectives in bioactive molecules.
متن کاملStereodivergent synthesis of two novel -aminophosphonic acids characterized by a cis-fused octahydroindole system
The synthesis of two new -aminophosphonic acids, namely (2S*,3aS*,7aS*)and (2R*,3aS*,7aS*)-octahydroindole-2phosphonic acids, is described. They are analogues of phosphoproline bearing a cyclohexane ring fused to the pyrrolidine moiety. The ring junction presents a cis stereochemistry in both cases, whereas the two compounds differ in the relative orientation of the cyclohexane and phosphonate...
متن کاملTransport of aminophosphonic acids in Lactobacillus plantarum and Streptococcus faecalis.
Aminophosphonic acids analogous to glutamic acid, aspartic acid, alanine, and valine were actively accumulated by Lactobacillus plantarum. Uptake was dependent on the availability of glucose and, in all cases, the estimated intracellular concentrations substantially exceeded extracellular levels. During uptake, there was little metabolism of tritiated 2-amino-3-phosphonopropionic acid (APP), th...
متن کاملStructural and morphological investigations of β-cyclodextrin-coated silver nanoparticles.
This paper describes the synthesis of silver nanoparticles using an aqueous silver nitrate solution in the presence of glucose as a reducing agent, sodium hydroxide as a reaction catalyst and β-CD as a stabilizer. The structure and the morphology associated to the stabilizing layer around the silver nanoparticles were investigated. Raman spectroscopy confirmed the nanoparticle surface modificat...
متن کاملReactivity of aminophosphonic acids. Oxidative dephosphonylation of 1-aminoalkylphosphonic acids by aqueous halogens.
The reactions of 1-aminoalkylphosphonic acids with bromine-water, chlorine-water and iodine-water were investigated. The formation of phosphoric(v) acid, as a result of a halogen-promoted cleavage of the Cα-P bond, accompanied by nitrogen release, was observed. The dephosphonylation of 1-aminoalkylphosphonic acids was found to occur quantitatively. In the reactions of 1-aminoalkylphosphonic aci...
