  • Patent number: 6441223
    Abstract: A process for oxidizing a hydroxymethylphosphonic acid compound to produce a formylphosphonic acid compound is described. The oxidation reaction is carried out in the presence of an oxidant and a catalyst. For example, hydroxymethylphosphonic acid (HMPA) is oxidized by oxygen or hydrogen peroxide in the presence of a copper-containing catalyst to give formylphosphonic acid (FPA). Formylphosphonic acid can then be reacted with glycine to produce a condensation product which, upon hydrogenation, yields glyphosate. Glyphosate can be incorporated into various formulations for use as a herbicide. In addition to glycine, formylphosphonic acid can also be reacted with ammonia, ethanolamine, or other primary amines to form a precursor compound, which can be converted to glyphosate.

    Abstract: An improved process for producing ethylenically unsaturated phosphate ester compounds, especially 2-(methacryloyloxyethyl)-2' (trimethylammoniomethyl) phosphate, (HEMA-PC) comprises a two step reaction in the first of which a phospholane reagent is reacted with a hydroxyl containing ethylenically unsaturated starting material, and in the second of which the intermediate formed in the first step is ring opened by reaction with trimethylamine to produce a zwitterionic product. In the process the two steps of the reaction are carried out in the same solvent with substantially no removal or addition of solvent after the first step. The solvent is preferably acetonitrile. The use of pure reagents avoids the production of undesirable by-products. The product is suitable for polymerising, for instance to provide cross-linked hydrogel copolymers used in ophthalmic applications.

  • Patent number: 5659061
    Abstract: The composition, synthesis, and applications of tumor associated protease activated prodrugs of phosphoramide mustard, isophosphoramide mustard and analogs with detoxification functionalities are described. These drugs release a cytotoxic phosphoramide mustard analog following activation by tumor associated proteases and esterases. The general structure for these drugs is: ##STR1## Wherein R1 is a beta-X-ethyl-amino group which may optionally bear substituents on the nitrogen or carbon atoms; wherein X is a good leaving group such as a halogen; R2 is a beta-X-ethyl-amino group which may optionally bear substituents on the nitrogen or carbon atoms; or an amino group (NH.sub.2) which may optionally be substituted. Wherein A is a benzyloxy derivative with one or more acyloxy or acylamino groups in para or ortho portions relative to the phosphoester; and wherein the acyloxy or acylamino groups are not (substituted or unsubstituted) p-guanidino-benzoyloxy groups or p-guanidino-benzoylamino groups.

  • Patent number: 5651981
    Abstract: A novel class of cationic phospholipids and novel method for their synthesis are disclosed. The class of phospholipids comprises phosphotriester derivatives of phosphoglycerides and sphingolipids. It has been unexpectedly found that liposomes comprising one or more of these cationic phospholipids are effective in the lipofection of nucleic acids. These novel phospholipids are particularly attractive because of they are not only effective in lipofection, but are extremely cheap and easy to make.
