The addition of trimethylsilyloxy phosphorus (III)derivatives generated in situ to imines at room temperature provides a mild selective and high yielding route to α-aminoalkylphosphorate and α-aminoalkylphenylphosphinate esters. Isocyanates and carbodiimides react similarly to give phosphonoureas and phosphonoguarnidines respectively aldehydes and ketones are much less reactive and cyanides are inert

The reaction of trialkylphosphites, dialkyl phenylphosphonites or alkyl diphenylphosphinites with N-alkylalkanimines in the presence of hydrogen chloride gives dialkyl 1-(alkylamino)alkylphosphonates, alkyl [1-(alkylamino)alkyl]phenylphosphinates or [1-(alkylamino)alkyl]diphenylphosphine oxides respectively, via Arbusov-like reaction of iminium salts generated ‘in situ’ from N-alkylalkanimines. This
The first solvent and catalyst free three-component coupling of carbonyl compounds, amines and triethylphosphite is achieved producing α-aminophosphonates at ambient temperature in very high yields.

[GRAPHICS]A simple, efficient, and general method has been developed for the synthesis of alpha-amino phosphonates through a one-pot reaction of aldehydes and ketones with amines in the presence of indium(III) chloride as a catalyst.

Fluorine-containing inhibitors of matrixmetalloproteinases (MMPs) can serve as lead structures for the development of 18F-labeled radioligands. These compounds might be useful as non-invasive imaging probes to characterize pathologies associated with increased MMP activity. Results with a series of fluorinated analogs of a known biphenyl sulfonamide inhibitor have shown that fluorine can be incorporated
