  • Patent number: 6846946
    Abstract: A method for preparing organic products from aqueous solutions, such as waste or byproduct liquid streams and waste or byproduct gas or vapor streams, uses phase transfer catalysis to transfer a chemical species in low concentration from the aqueous solution to the organic phase or the aqueous-organic interface. The system has little or no organic solvent, and the organic phase contains an electrophile which participates in the reaction. In one embodiment, the aqueous solution is contacted with the electrophile and a phase transfer catalyst and, optionally, a pH adjusting agent in the event that the chemical species in the aqueous solution is not sufficiently ionized to react with the electrophile, and optionally an organic solvent. A method for continuously converting a chemical species involves this contacting step, separating the phases, then dividing the organic phase into the product, the phase transfer catalyst, and the optional organic solvent.

  • Patent number: 6809089
    Abstract: The present invention relates to compounds of the formula I in which A1, A2, R2 and R3 have the meanings indicated in the claims, which are valuable pharmaceutical active compounds for the therapy and prophylaxis of diseases, for example of cardiovascular disorders such as high blood pressure, angina pectoris, cardiac insufficiency, thromboses or atherosclerosis. The compounds of the formula I have the ability to modulate the endogenous production of cyclic guanosine monophosphate (cGMP) and are generally suitable for the therapy and prophylaxis of disease states which are associated with a disturbed cGMP balance. The invention relates to the use of compounds of the formula I for the therapy and prophylaxis of the designated disease states and for the production of pharmaceuticals therefor, novel compounds of the formula I, pharmaceutical preparations comprising them and processes for their preparation.

  • Patent number: 6774236
    Abstract: The invention relates to a process and intermediates for the preparation of enantiomerically pure cycloalkanoindolecarboxylic acids and azaindolecarboxylic acids and pyrimido[1,2a]indolecarboxylic acids and their activated derivatives, characterized in that the tolyl acetic acid is first esterified with a chiral alcohol, then diastereoselective substitution at &agr;-carbon atoms is carried out and this product is halogenated in the tolyl group and then reacted with appropriate cycloalkanoindoles, cycloalkanoazaindoles or pyrimido[1,2a]indoles. It is possible by this method to prepare specifically, in high purity, the enantiomerically pure carboxylic acids which are intermediates for valuable medicaments.

  • Publication number: 20040110089
    Abstract: Novel anti-reflective coatings comprising small molecules (e.g., less than about 5,000 g/mole) in lieu of high molecular weight polymers and methods of using those coatings are provided. In one embodiment, aromatic carboxylic acids are used as the chromophores, and the resulting compounds are blended with a crosslinking agent and an acid. Anti-reflective coating films prepared according to the invention exhibit improved properties compared to high molecular weight polymeric anti-reflective coating films. The small molecule anti-reflective coatings have high etch rates and good via fill properties. Photolithographic processes carried out with the inventive material result in freestanding, 110-nm profiles.
