The Kabachnik-Fields (phospha-Mannich) reaction involving the condensation of primary or secondary amines, oxo compounds (aldehydes and ketones) and >P(O)H species, especially dialkyl phosphites, represents a good choice for the synthesis of α-aminophosphonates that are of significant importance due to their biological activity. In general, these three-component reactions may take place via a...

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.

[1]Rotaxanes based on monosubstituted phosphorus-containing pillar[5]arenes have been synthesized by the Kabachnik–Fields reaction for first time in good yields.

A novel series of ribonucleosides of 1,2,3-triazolylbenzyl-aminophosphonates was synthesized through the Kabachnik-Fields reaction using I2 as catalyst followed by copper-catalyzed cycloaddition of the azide-alkyne reaction (CuAAC). All structures of the newly prepared compounds were characterized by (1) H NMR, (13) C NMR, and HRMS spectra. The structures of 2e, 2f, 3d, and 3g were further conf...
