Synthesis of alkyl hydrogen (1-aminoalkyl)phosphonates
摘要:
Addition of hypophosphorous acid to aldoximes affords (1-aminoalkyl)phosphinic acids which on treatment with bromine in alkanols are transformed into alkyl hydrogen (1-aminoalkyl)phosphonates.

magnesium ions. These two properties of phosphinate pseudopeptides make them an ideal candidate for metal-related protease inhibitors. This research investigates the influence of additional residue in the P2 position on the inhibitory properties of phosphinopeptides. The synthetic strategy is proposed, based on retrosynthetic analysis. The N-C-P bond formation in the desired compounds is conveniently available

A variety of phosphorus amino acid and dipeptide analogues have been synthesized and evaluated as inhibitors of the metalloenzyme leucine aminopeptidase from porcine kidney. Two phosphonate dipeptides were found to be modest inhibitors of the enzyme (8e, Ki = 58 microM; 8h, Ki = 340 microM). The phosphinicacid (17-OH) and phosphinamide (17-NH2) analogues related to bestatin were prepared by condensation
