标题:Two Chemodivergent Anionic Domino Processes From Cyclic α-Nitroketones And Aromatic Aldehydes
摘要:Treatment Of Cyclic Alpha-Nitroketones And Aromatic 1,2-Dialdehydes With Dbu In Tetrahydrofuran Containing Small Amounts Of Water Proceeded Through Two Chemodivergent One-Pot Domino Pathways,Whose Outcome Depended On The Ring Size Of The Starting Nitroketone. Thus,Alpha-Nitrocyclohexanone Underwent Diastereoselective Alpha'-Arylmethylenation Reactions Through A Nitroaldol/aldol/reverse Nitroaldol Mechanism. On The Other Hand,Alpha-Nitrocycloheptanone And Alpha-Nitrocyclooctanone Afforded 2-Nitroindane-1,2-Diols Containing Three Contiguous Stereocenters In A Highly Diastereoselective Fashion Through A Nitroaldol/retro-Dieckmann/intramolecular Nitroaldol Process.

标题 :Conjugated thiophenes having conducting properties and synthesis of same
发明人：SKENE WILLIAM G
权利人:UNIV MONTREAL
摘要:The present invention relates to conjugated oligomers and polymers comprising aromatic thiophene cores. The conjugated materials are obtained by simple and efficient condensation of an aryl diamine and an aryl dialdehyde or a bifunctional aryl moiety comprising both an aldehyde and an amine. Condensation of the complementary moieties at temperatures ranging from ambient to refluxing temperatures in various solvents resulted in conjugated oligomers and polymers that can subsequently be cast into thin films. Oligomerization and polymerization can be done under mild conditions with removal of the resulting water bi-product responsible for shifting the equilibrium in favor of the conjugated products. The resulting conjugated compounds can be made conducting with dopants affording electrically conducting materials of either p-type or n-type conductors depending on the dopant selected.

摘要:This invention relates to novel multibinding compounds (agents) that are antibacterial agents. The multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands in their monovalent (i.e., unlinked) state have the ability to bind to a an enzyme involved in cell wall biosynthesis and metabolism, a precursor used in the synthesis of the bacterial cell wall and/or the bacterial cell surface thereby interfere with the synthesis and/or metabolism of the cell wall. In particular the multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands hasn a ligand domain capable of binding to penicillin binding proteins, a transpeptidase enzyme, a substrate of a transpeptidase enzyme, a beta-lactamase enzyme, pencillinase enzyme, cephalosporinase enzyme, a transglycoslase enzyme, or a transglycosylase enzyme substrate; Preferably, the ligands are selected from the beta lactam or glycopeptide class of antibacterial agents.

摘要:Disclosed are semiconducting or conducting organic small molecules and oligomers that contain a central, electron rich, functionalized dihydrodicyclopentylanthracene core (or electron donor core) that is connected to at least one or two comparatively electron deficient monomeric unit or units (or electron acceptor units) that feature group 16 heteroatoms sulfur, selenium or tellurium or combinations thereof. Multiple electron rich cores can be linked together through one or more alkynyl linkages. The small molecules and oligomers can have the following generic structure and can be used in areas such as organic photovoltaic materials:
