In diagnostic microbiology, culture media are widely used for detection of pathogenic bacteria. Such media employ various ingredients to optimize detection of specific pathogens such as chromogenic enzyme substrates and selective inhibitors to reduce the presence of commensal bacteria. Despite this, it is rarely possible to inhibit the growth of all commensal bacteria, and thus pathogens can be overgrown and remain undetected. One approach to attempt to remedy this is the use of “suicide substrates” that can target specific bacterial enzymes and selectively inhibit unwanted bacterial species. With the purpose of identifying novel selective inhibitors, six novel phosphonopeptide derivatives based on D/L-fosfalin and β-chloro-L-alanine were synthesized and tested on 19 different strains of clinically relevant bacteria. Several compounds show potential as useful selective agents that could be exploited in the recovery of several bacterial pathogens including Salmonella, Pseudomonas aeruginosa, and Listeria.
1-(Acylamino)alkylphosphonic acids—alkaline deacylation
Cypryk, Marek,Drabowicz, Jozef,Gostynski, Bartlomiej,Kudzin, Marcin H.,Kudzin, Zbigniew H,Urbaniak, Pawel

The alkaline deacylation of a representative series of 1-(acylamino)alkylphosphonic acids [(AC)-AAP: (AC) = Ac, TFA, Bz; AAP = GlyP, AlaP, ValP, PglP and PheP] in an aqueous solution of KOH (2M) was investigated. The results suggested a two-stage reaction mechanism with a quick interaction of the hydroxyl ion on the carbonyl function of the amide R-C(O)-N(H)- group in the first stage, which leads to instant formation of the intermediary acyl-hydroxyl adducts of R-C(O?)2-N(H)-, visible in the 31P NMR spectra. In the second stage, these intermediates decompose slowly by splitting of the RC(O?)2-N(H)- function with the subsequent formation of 1-aminoalkylphosphonate and carboxylate ions.

The 1-(N-acylamino)alkylphosphonic acids (AC)-AAP belong to the interesting and potentially of pharmacological importance group of 1-aminoalkylphosphonic acids derivatives. Since susceptibility of (AC)-AAP on hydrolytic deacylation can form important factor influencing their biological activity, we have undertaken deacylation investigations of these compounds in aqueous media. In this article, we present our results on deacylation of various types of 1-(N-acylamino)alkylphosphonic acids (AC)-AAP, including 1-(N-acetylamino)alkyl-phosphonic Ac-AAP, 1-(N-chloroacetylamino)alkylphosphonic acids Mca-AAP, 1-(N-trifluoroacetylamino)alkylphosphonic acids TFA-AAP, and 1-(N-benzoylamino)-alkylphosphonic Bz-AAP, derived from representative 1-aminoalkylphosphonic acids AAP (GlyP, AlaP, ValP, PglP, and PheP) in neutral and 2?M HCl solutions.
Conversion of nitriles to 1-aminophosphonic acids and preparation of phosphahomocysteines of high enantiomeric excess

, p. 737 - 744 (2017/06/05)
A variety of nitriles was reduced to diisobutylaluminum salts of aldimines, to which diisopropyl phosphite was added. The corresponding 1-aminophosphonates were either deprotected to give racemic 1-aminophosphonic acids or reacted with Boc2O to yield N-Boc-protected 1-aminophosphonates. The enantiomers of 2-benzylthio-1-(t-butoxycarbonylamino)propylphosphonate were obtained from the racemate by chiral HPLC and converted to phosphonic acid analogs of (R)- and (S)-homocysteine, (R)- and (S)-2-aminobutyric acid and (S)-methionine, all of ee >97% as determined by chiral HPLC.

Goldeman, Waldemar,Soroka, Miroslaw
experimental part, p. 360 - 369 (2011/02/27)
The reaction of phosphorus trichloride in acetic acid or phosphonic (phosphorous) acid in acetic anhydride, with N-(triphenylmethyl)alkanimines gives 1-acetylaminoalkylphosphonic acids 1a-j, which after hydrolysis give 1-aminoalkylphosphonic acids 2a-j in good yields. ARKAT USA, Inc.

Application of silicon-phosphorus based reagents in synthesis of aminophosphonates. Part 2: Reactions of N-(Triphenylmethyl)-aldimines with the silylated phosphorus acid esters
Boduszek,Soroka
, p. 1105 - 1111 (2007/10/03)
Reactions of silylated phosphorus acid esters with N-triphenylmethylaldimines (N-tritylaldimines) were investigated. N-Tritylmethaneimine reacts at room temperature with a mixture of P(OMe)3 and Me3SiBr forming the corresponding aminophosphonate derivatives in high yield. Other N-tritylimines are resistant toward the silylated reagents at room temperature, but undergo a similar phosphorylation reaction at elevated temperatures to form the expected aminophosphonic acids.
The formation of α-amino- and α-hydroxy-alkanephosphonic acids in the reactions of phosphite esters with aldehydes and alkyl carbamates
Hudson, Harry R.,Ismail, Fatima,Pianka, Max,Wan, Chi-Wai
, p. 245 - 257 (2007/10/03)
The preparation of α-aminoalkanephosphonic acids from triphenyl phosphite, an aldehyde, and ethyl or benzyl carbamate in glacial acetic acid, followed by hydrolysis, is accompanied by the formation of the corresponding α-hydroxyphosphonic acid. Reaction in toluene, using boron trifluoride-etherate as catalyst, affords an alternative preparative procedure but does not prevent the formation of α-hydroxyphosphonic acid. 31P nmr reveals the presence of numerous intermediates. The reactions are discussed.

, p. 407 - 410 (2007/10/02)
A new procedure has been developed for the synthesis of 1-aminophosphonic acids. Diethyl phosphonates are converted to hydroxyiminophosphonates when treated with hydroxylamine hydrochloride. Reduction of hydroiminophosphonates with NaBH4 in MeOH in the presence of MoO3 or NiCl2 and hydrolysis of 1-aminophosphonates gave 1-aminophosphonic acids in good yields.
Preparation of 1-aminoalkylphosphonic acids and 2-aminoalkylphosphonic acids by reductive amination of oxoalkylphosphonates
Ryglowski, Artur,Kafarski, Pawel
, p. 10685 - 10692 (2007/10/03)
By reacting dialkyl 1-oxo- or 2-oxoalkylphosphonates with benzhydrylamine followed by reduction with triacetoxyborohydride and acid hydrolysis gave corresponding aminoalkylphosphonic acids with satisfactory yields. The use of benzylamine, α-methylbenzylamine and tritylamine was unsuccessful in the case of dialkyl 1-oxoalkylphosphonates whereas conversion of 2-oxoalkylphosphonates was also achieved although with lower yields.
