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.
Conversion of nitriles to 1-aminophosphonic acids and preparation of phosphahomocysteines of high enantiomeric excess

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.
Tritylamine (triphenylmethylamine) in organic synthesis; III. The synthesis of 1-aminoalkylphosphonic acids in the reaction of N-(triphenylmethyl) alkanimines with phosphorus trichloride in acetic acid or with phosphonic (phosphorous) acid in acetic anhydride

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.
