“…The bioassay results showed that the racemate possessed good antiviral and antitumor activities. [36][37][38][39][40] As different chiral aminophosphonates and their derivatives display varying bioactivities, screening of fluorine derivatives bearing a-amiophosphonate moieties might lead to new antiviral agent with more potent antiviral activities. Keeping these considerations in mind, herein a series of new fluorine containing bioactive chiral a-aminophosphonates were asymmetrically synthesized using chiral Bronsted acid organocatalyst 3 7,41-45 derived from (R)-or (S)-BINOL 46 in a typical hydrophosphonylation reaction of aldimines obtained from cinnamaldehyde and fluorinated aromatic amine with dialkyl phosphites.…”

Asymmetric addition of dialkyl phosphites (--CH2CH3, --CH2CH2CH3, --CH(CH3)2, --CH2(CH2)3CH3, --CH2CH2OCH3 and --CH2CH2OC2H5) induced by chiral organocatalyst e.g. (R)- and (S)-3,3'-[3,5-bis(trifluoromethyl)phenyl]2-1,1'-binaphthyl phosphate on fluorinated aldimines derived from cinnamaldehyde has been found effective to give new bioactive alpha-aminophosphonates in good yields (58-73%) and high enantiomeric excess (64.6%-90.6%) under mild conditions.

“…However, the antibacterial activity of α-aminophosphonates has been reported in the literature against gram-positive and gram-negative bacteria, [9][10][11][12] but the new synthesized compounds in this paper had MIC more than 256 µg/ ml against the investigated bacteria. It has been reported that pharmacological effects of α-aminophosphonates are sterospecific; [8] therefore, we suggest that antibacterial effect of these compounds may be stereoselective and the antibacterial evaluation of each enantiomer separately can confirm this matter.…”

[16] Also, the activities of α-aminophosphonates as peptidomimetics, [17] enzyme inhibitors, [18] haptens of catalytic antibodies, [19] herbicidals, [20] inhibitors of serine hydrolases [21] and inhibitors of UDP-galactopyranose mutase [22] are reported in literature.…”

Background: α-Aminophosphonates are bioisosters of amino acids and have several pharmacological effects. α-Aminophosphonates have been synthesized by various routes from reaction between an amine, an aldehyde, and phosphate compounds. Materials and Methods: We synthesized 20 new α-aminophosphonates in the presence of FeCl3 in THF as a catalyst to facilitate the Manich-type reaction of aldehyde, amine and phosphite compounds to form the corresponding α-aminophosphonates in a one-pot, three-component reaction. In this study, the catalytic effect of ZnCl2 was also compared with FeCl3 in the synthesis of α-aminophosphonates. Results: The results showed that FeCl3 catalyzed the reaction in mild conditions to form α-aminophosphonates with high yields, but ZnCl2 did not give high yields of the compounds and the reaction took longer time in comparison to that taken by FeCl3 The chemical structures of all new compounds were confirmed by spectrophotometric methods (1HNMR, 13CNMR, IR). The compounds were investigated for antimicrobial activity against Escherichia coli, Bacillus subtilis, Salmonella typhi, Shigella sonnei, Proteus vulgaris, and Staphylococcus epidermidis. Conclusion: The new synthesized compounds did not show good antibacterial activity against the tested microorganisms

Alkyl 2-cyano-3-methylthio-3-phosphonylacrylates were synthesized by the reaction of alkyl 2-cyano-3,3-dimethylthioacrylates with dialkyl phosphites. The structures of the new compounds were characterized by elemental analyses, IR, 1 H-, 13 C-and 31 P-NMR spectral data. These compounds were tested in vitro against pathogenic fungi, namely, Fusarium graminearum, Cytospora mandshurica and Fusarium oxysporum. Amongst all compounds, 2d and 2t were found to be effective against the tested fungi at 50 µg/mL. A half-leaf method was used to determine the in vivo protective, inactivation and curative efficacies of the title products against tobacco mosaic virus (TMV). Title compounds 2a and 2b were found to possess good in vivo curative, protection and inactivation effects against TMV with inhibitory rates at 500 mg/L of 60.0, 89.4 and 56.5 and 64.2, 84.2 and 61.2 %, respectively. To the best of our knowledge, this is the first report on the antiviral and antifungal activity of alkyl 2-cyano-3-methylthio-3-phosphonylacrylates.
