  • Patent number: 8097760
    Abstract: This invention provides a convenient method for converting oximes into enamides. The process does not require the use of metallic reagents. Accordingly, it produces the desired compounds without the concomitant production of a large volume of metallic waste. The enamides are useful precursors to amides and amines. The invention provides a process to convert a prochiral enamide into the corresponding chiral amide. In an exemplary process, a chiral amino center is introduced during hydrogenation through the use of a chiral hydrogenation catalyst. In selected embodiments, the invention provides methods of preparing amides and amines that include the 1,2,3,4-tetrahydro-N-alkyl-1-naphthalenamine or 1,2,3,4-tetrahydro-1-naphthalenamine substructure.

  • Patent number: 8097750
    Abstract: The instability of carbamate-protected alkyl imines has greatly hampered the development of catalytic asymmetric Mannich reactions suitable for the synthesis of optically active carbamate-protected chiral alkyl amines. A highly enantioselective Mannich reaction with in situ generation of carbamate-protected imines from stable ?-amido sulfones catalyzed by an organic catalyst has been developed. This reaction provides a concise and highly enantioselective route converting aromatic and aliphatic aldehydes into optically active aryl and alkyl ?-amino acids.

  • Patent number: 8088346
    Abstract: A reductive cross coupling reaction process for functionalization of a nucleophilic alkene can be achieved. The nucleophilic alkene and a nucleophilic cross coupling partner compound can be reacted in the presence of an oxidizable alcohol and a suitable catalyst to form a reductive coupling product. Various additives can also be useful to refine the process such as by mitigating certain undesirable intermediates, facilitating specific site selectivity for various substitutions or reaction sites, etc. Chiral additives can be optionally used which act to provide asymmetric catalysis, e.g. allow for regioselective and stereoselective production of reductive coupling products. A reductive cross coupling pathway can include oxidizing the oxidizable alcohol to form a catalyst hydride. The nucleophilic alkene can be inserted into the catalyst hydride to form a catalyst-alkyl intermediate.

  • Patent number: 8084647
    Abstract: A two-photon probe for real-time monitoring of intracellular calcium ions is provided. The two-photon probe is very suitable for real-time imaging of intracellular calcium ions, shows 20˜50-fold TPEF enhancement in response to Ca2+, has a dissociation constant (KdTP) of 0.14±0.02 to 0.25±0.03 ?M, and emits 5-fold stronger TPEF than currently available one-photon fluorescent Ca2+ probes. Unlike the previously available probes, the two-photon probe can selectively detect dynamic levels of intracellular free Ca2+ in live cells and living tissues without interference from other metal ions and from the membrane-bound probes. Moreover, the two-photon probe is capable of monitoring the calcium waves at a depth of 100-300 ?m in live tissues for 1,100-4,000 s using two-photon microscopy (TPM) with no artifacts of photo-bleaching. Further provided are a method for preparing the two-photon probe and a method for real-time monitoring of intracellular calcium ions using the two-photon probe.

  • Patent number: 8084653
    Abstract: Disclosed are processes for the production of fluorinated olefins, preferably adapted to commercialization of CF3CF?CH2 (1234yf). Three steps may be used in preferred embodiments in which a feedstock such as CCl2?CClCH2Cl (which may be purchased or synthesized from 1,2,3-trichloropropane) is fluorinated (preferably with HF in gas-phase in the presence of a catalyst) to synthesize a compound such as CF3CCl?CH2, preferably in a 80-96% selectivity. The CF3CCl?CH2 is preferably converted to CF3CFClCH3 (244-isomer) using a SbCl5 as the catalyst which is then transformed selectively to 1234yf, preferably in a gas-phase catalytic reaction using activated carbon as the catalyst. For the first step, a mixture of Cr2O3 and FeCl3/C is preferably used as the catalyst to achieve high selectivity to CF3CCl?CH2 (96%). In the second step, SbCl5/C is preferably used as the selective catalyst for transforming 1233xf to 244-isomer, CF3CFClCH3.

  • Patent number: 8063242
    Abstract: (R) and (S) 2-Aryl-propionic acids, and pharmaceutical compositions that contain them, are useful in inhibiting chemotactic activation of neutrophils (PMN leukocytes) induced by the interaction of Interleukin-8 (IL-8) with CXCR1 and CXCR2 membrane receptors. The acids are used for the prevention and treatment of pathologies deriving from said activation. In particular, the (R) enantiomers of said acids are lacking cyclo-oxygenase inhibition activity and are particularly useful in the treatment of neutrofil-dependent pathologies such as psoriasis, ulcerative colitis, melanoma, chronic obstructive pulmonary disease (COPD), bollous pemphigo, rheumatoid arthritis, idiopathic fibrosis, glomerulonephritis and in the prevention and treatment of damages caused by ischemia and reperfusion.
