  • Patent number: 11960832
    Abstract: Machine learning, artificial intelligence, and other computer-implemented methods are used to identify various semantically important chunks in documents, automatically label them with appropriate datatypes and semantic roles, and use this enhanced information to assist authors and to support downstream processes. Chunk locations, datatypes, and semantic roles can often be automatically determined from what is here called “context”, to wit, the combination of their formatting, structure, and content; those of adjacent or nearby content; overall patterns of occurrence in a document, and similarities of all these things across documents (mainly but not exclusively among documents in the same document set).

  • Publication number: 20220215410
    Abstract: Systems and methods for predictive analytics may make innovation success easy to manage by predicting the best process and teams to help teams discover if their ideas can reach ideal outcomes. Leadership may make a portfolio of investments in opportunity areas. Each opportunity area's funds may be broken down into different bets. Each bet fund may have success criteria to determine if an opportunity can continue to the next stage of funding. Each success metric may have blocks that help take ideas to success. Systems and methods may recommend the best block path to success for each idea. Blocks may be recommended based on context including, but not limited to, progress, goals, priorities, team dynamics, and skills. These systems and methods also may empower people to drive success, while engaging interests, saving hours, and eliminating wrong work. Good decisions may be made to maximize ROI, thereby creating innovation success.

  • Patent number: 10611786
    Abstract: Reactions that directly install nitrogen into C—H bonds of complex molecules are significant because of their potential to change the chemical and biological properties of a given compound. Selective intramolecular C—H amination reactions that achieve high levels of reactivity, while maintaining excellent site-selectivity and functional-group tolerance is a challenging problem. Herein is reported a manganese perchlorophthalocyanine catalyst [MnIII(ClPc)] for intermolecular benzylic C—H amination of bioactive molecules and natural products that proceeds with unprecedented levels of reactivity and site-selectivity. In the presence of Brønsted or Lewis acid, the [MnIII(ClPc)]-catalyzed C—H amination demonstrates unique tolerance for tertiary amine, pyridine and benzimidazole functionalities. Mechanistic studies indicate that C—H amination proceeds through an electrophilic metallonitrene intermediate via a stepwise pathway where C—H cleavage is the rate-determining step of the reaction.

  • Patent number: 10266503
    Abstract: The enantioselective synthesis of isochroman motifs has been accomplished via Pd(II)-catalyzed allylic C—H oxidation from terminal olefin precursors. Critical to the success of this goal was the development and utilization of a novel chiral aryl sulfoxide-oxazoline (ArSOX) ligand. The allylic C—H oxidation reaction proceeds with the broadest scope and highest levels asymmetric induction reported to date (avg. 92% ee, 13 examples ?90% ee). Additionally, C(sp3)-N fragment coupling reaction between abundant terminal olefins and N-triflyl protected aliphatic and aromatic amines via Pd(II)/sulfoxide (SOX) catalyzed intermolecular allylic C—H amination is disclosed. A range of 52 allylic amines are furnished in good yields (avg. 76%) and excellent regio- and stereoselectivity (avg. >20:1 linear:branched, >20:1 E:Z).

  • Patent number: 9925528
    Abstract: The invention provides simple small molecule, non-heme iron catalyst systems with broad substrate scope that can predictably enhance or overturn a substrate's inherent reactivity preference for sp3-hybridized C—H bond oxidation. The invention also provides methods for selective aliphatic C—H bond oxidation. Furthermore, a structure-based catalyst reactivity model is disclosed that quantitatively correlates the innate physical properties of the substrate to the site-selectivities observed as a function of the catalyst. The catalyst systems can be used in combination with oxidants such as hydrogen peroxide to effect highly selective oxidations of unactivated sp3 C—H bonds over a broad range of substrates.

  • Patent number: 9770711
    Abstract: The invention provides novel manganese catalysts such as [Mn(tBuPc)], which are general for the amination of all types of C(sp3)-H bonds (aliphatic, allylic, propargylic, benzylic, ethereal), including strong 1o aliphatic C—H bonds, while achieving excellent chemoselectivity, stereospecificity, and high functional group tolerance. We demonstrate the late-stage diversification of bioactive complex molecules that encompass the range of C(sp3)-H bond types, such as selective 1o C—H aminations of betulinic acid and pleuromutilin derivatives. The catalysts' unprecedented balance of reactivity and selectivity is in part attributed to its mechanism of C—H amination that lies between stepwise and concerted.

  • Publication number: 20110015397
    Abstract: A composition including a complex of a metal, a tetradentate ligand, at least one ancillary ligand, and a counterion may be used for selective sp3 C—H bond oxidation. The tetradentate ligand may include a N-heterocyclic-N,N?-bis(pyridyl)-ethane-1,2-diamine group or a N,N?-bis(heterocyclic)-N,N?-bis(pyridyl)-ethane-1,2-diamine group. The composition can be used in combination with H2O2 to effect highly selective oxidations of unactivated sp3 C—H bonds over a broad range of substrates. The site of oxidation can be predicted, based on the electronic and/or steric environment of the C—H bond. In addition, the oxidation reaction does not require the presence of directing groups in the substrate.

  • Publication number: 20080260834
    Abstract: Localized delivery of 1,25 D3 directly to a target area using biodegradable polymeric matrices maximizes the efficacy of this drug while minimizing systemic exposure and toxicity. Anticalcemic analogs of 1,25 D3 have also been incorporated into controlled release polymer formulations to achieve efficacious intracranial concentrations of 1,25 D3 analogs for the treatment of intracranial tumors as well as neurodegenerative disorders such as Alzheimer's disease as well as to maximize the efficacy of these analogs in the treatment of systemic malignancies. The therapeutic efficacy of these formulations was demonstrated through a variety of studies in vitro and in vivo. Hybrid analogs of 1,25 D3 were incorporated into biodegradable polymer wafers composed of a polyanhydride copolymer of 1,3-bis(p-carboxyphenoxy)propane (CPP) and sebacic acid (SA) in a 20:80 molar ratio.
