In this study, Michaelis-Arbuzov-type reaction of 1-imidoalkyltriarylphosphonium salts with phosphites, phosphonites, and phosphinites was used in the synthesis of a wide range of phosphorus analogs of α-amino acids such as 1-imidoalkylphosphonates, 1-imidoalkylphosphinates, and 1-imidoalkylphosphine oxides. Large differences were observed in the reactivity of substrates depending on their structure, especially on the type of phosphonium moiety and N-protecting group. The conditions under which the expected products can be obtained in good to excellent yields have been developed. Mechanistic aspects of the transformation have been provided.

A series of phthalimido phosphor derivatives α-amino-phosphonates, amidophosphonates, phosphonic acid diamides, and oxadiazaphospholes-were prepared by applying different types of phosphorus(III) reagents to 2-methoxy-1H-isoindole-1,3(2H)-dione and 2-anilino-1H-isoindole-1,3(2H)-dione. On the basis of bioassay results, some of the new phosphoryl imides could be considered as lead molecules to be modified in order to improve their antibiotic activity. Springer-Verlag 2010.

-
, (2008/06/13)
The compounds of this invention are cephalosporins having various acylamino substituents at the 7-position and a phosphonoalkyl or esterified phosphonoalkyl substituted tetrazolylthiomethyl group at the 3-position of the cephem nucleus and intermediates for the preparation thereof. The 7-acylated compounds have antibacterial activity.
