  • Publication number: 20030109713
    Abstract: A process for producing organic substituted aromatic or heteroaromatic compounds including biaryl and biheteroaryl compounds in a two-step reaction. In the first step, the aromatic or heteroaromatic compound is borylated in a reaction comprising a borane or diborane reagent (any boron reagent where the boron reagent contains a B—H, B—B or B—Si bond) and an iridium or rhodium catalytic complex. In the second step, a metal catalyst catalyzes the formation of the organic substituted aromatic or heteroaromatic compound from the borylated compound and an electrophile such as an aryl or organic halide, triflate (OSO2CF3), or nonaflate (OSO2C4F9). The steps in the process can be performed in a single reaction vessel or in separate reaction vessels. The present invention also provides a process for synthesis of complex polyphenylenes starting from halogenated aromatic compounds.

  • Publication number: 20010006619
    Abstract: The present invention relates to a class of compounds having affinity for certain cancer cells, e.g. lung carcinomas, colon carcinomas, renal carcinomas, prostate carcinomas, breast carcinomas, malignant melanomas, gliomas, neuroblastomas and pheochromocytomas. The compounds of the present invention can also bind with high specificity to cell surface sigma receptors and can therefore be used for diagnostic imaging of any tissue having an abundance of cells with sigma receptors. The present invention provides such compounds as agents for diagnostic imaging and for detecting and treating tumors containing the cancer cells described above.

  • Patent number: 6153766
    Abstract: 4-Hydroxy-2-pyrrolidinone which is useful as a raw material of drugs can be produced rapidly and highly selectively in a high yield from an optically active or recemic 4-amino-3-hydroxybutylic acid derivative or a 4-azido-3-hydroxybutyric acid derivative by adding a base catalyst to the reaction system. 4-Hydroxy-2-pyrrolidinone having a high optical purity can be obtained by carrying out recrystallization of optically active 4-hydroxy-2-pyrrolidinone without using a poor solvent.

  • Patent number: 6002003
    Abstract: Activating groups for cyanine dyes used to label chain terminators in nucleotide sequencing, based on N-hydroxyphthalimide, are disclosed. From these activating groups, activated dyes of the present Invention are prepared which react with the derivitized nucleotide chain terminators to give a labeled chain terminator of the present Invention. The activating groups of the present Invention allow the dye-chain terminator reaction to occur at a much higher yield and with much greater selectivity for the mono-substituted product, compared with the prior art.
