The synthesis of α-aryl-α-aminophosphonates and α-aryl-α-aminophosphine oxides by the microwave-assisted Pudovik reaction
A family of α-aryl-α-aminophosphonates and α-aryl-α-aminophosphine oxides was synthesized by the microwave-assisted solvent-free addition of dialkyl phosphites and diphenylphosphine oxide, respectively, to imines formed from benzaldehyde derivatives and primary amines. After optimization, the reactivity was mapped, and the fine mechanism was evaluated by DFT calculations. Two α-aminophosphonate...
متن کاملDesign, Synthesis, and Antifungal Activity of New α-Aminophosphonates
α-Aminophosphonates are bioisosteres of amino acids and have several pharmacological activities. These compounds have been synthesized by various routes from reaction between amine, aldehyde, and phosphite compounds. In order to synthesize α-aminophosphonates, catalytic effect of CuCl2 was compared with FeCl3. Also all designed structures as well as griseofulvin were docked into the active site...
متن کاملSynthesis and Antiviral Bioactivities of α-Aminophosphonates Containing Alkoxyethyl Moieties
A simple, efficient, and general method has been developed for the synthesis of various α-aminophosphonate derivatives 4a-4l by treatment of substituted benzaldehydes and aniline with bis(2-methoxyethyl)or bis(2-ethoxyethyl) phosphite under microwave irradiation without solvents and catalysts. The products were characterized by elemental analysis, IR, H-NMR, Cand P-NMR spectra. The X-ray crysta...
متن کاملA highly efficient bismuth salts-catalyzed route for the synthesis of α-aminophosphonates.
A convenient synthesis of different types of α-amino phosphonates via one-pot solvent-free three component reactions of aldehydes, amines and phosphites catalyzed by bismuth salts has been investigated. Bismuth triflate is found to be the most effective catalyst for this reaction.
متن کاملOne-pot synthesis, characterization and of antimicrobial activity of α- aminophosphonates
α-Aminophosphonates (4a-h) were synthesized in one-pot simultaneous reaction of aniline(1), dimethylphosphite(3), and different aromatic aldehydes (2) by Kabachnik–Fields reaction in ethanol at room temperature. The products (4a-h) were obtained in good yields. All these compounds were found to exhibit moderate to good antimicrobial activity.
