Reaction of alpha-oximinophosphonates first with acetic anhydride then with iron powder and acetic acid at 50-60 degreesC results in the clean formation of an E-Z mixture of alpha-phosphonoenacetamides. which are immediate precursors to alpha-ammophosphonic acids.

Lanthionine ketimine derivatives, and methods of making and using the same, are described. Included are lanthionine ketimine phosphonate (LK-P), lanthionine ketimine ester phosphonate (LKE-P) derivatives, as well as lanthionine ketimine derivatives having a tert-enamide moiety at the 2-position (NVP-LKE).

The multiple-step, one-pot procedure for a series of 2-substituted-3-phosphono-1-thia-4-aza-2-cyclohexene-5-carboxylates, analogues of the natural, sulfur amino acid metabolite lanthionine ketimine (LK), its 5-ethyl ester (LKE) and 2-substituted LKEs is described. Initiating the synthesis with the Michaelis-Arbuzov preparation of α-ketophosphonates allows for a wide range of functional variation at

N-alpha-haloacylated homoserine lactones, in which a halogen atom was introduced at the alpha-position of the carbonyl function of the N-acyl chain, have been studied as quorumsensing (QS) modulators and compared with a library of natural N-acylated homoserine lactones (AHLs). The series of novel analogues consists of alpha-chloro, alpha-bromo and alpha-iodo AHL analogues. Furthermore, the biological QS activity of
allowing effective control of the end of the reaction and identification of all phosphorylated intermediate species, which enabled us to propose a reaction mechanism. Optimized experimental conditions were applied to the preparation of biological relevant aminoalkyl-HMPPs. A preliminary study of the complexation to hydroxyapatite (bone matrix) was carried out in order to verify its lower affinity towards
