• Synthesis of Functional Olefin Copolymers with Controllable Topologies Using a Chain-Walking Catalyst
  作者：Guanghui Chen、Xun S. Ma、Zhibin Guan

  DOI：10.1021/ja028921s

  日期：2003.6.1

  The branching topology of ethylene polar copolymers was for the first time successfully controlled by copolymerization of ethylene with polar olefins using a palladium-bisimine chain-walking catalyst, in which ethylene pressure and comonomer concentration were used to control the competition between isomerization (chain-walking) and monomer insertion processes. Although the overall branching density changes very slightly, the topology of the copolymers becomes more dendritic as the ethylene pressure and comonomer feed concentration are decreasing. This provides a straightforward one-pot synthesis to access a full range of functional copolymers having controllable branching topologies. To demonstrate the utility of this methodology, dendritic functional copolymers having hydroxyl, epoxide, and carbohydrate groups were prepared in a one-pot polymerization as potential functional materials.
• Rh-Catalyzed Enantioselective Diboration of Simple Alkenes:  Reaction Development and Substrate Scope
  作者：Stéphane Trudeau、Jeremy B. Morgan、Mohanish Shrestha、James P. Morken

  DOI：10.1021/jo051651m

  日期：2005.11.1

  The rhodium-catalyzed reaction between bis(catecholato)diboron and simple alkenes results in the syn addition of the diboron across the alkene. The resulting 1,2-bis(boronate) is subsequently oxidized to provide the 1,2-diol. In the presence of enantiomerically enriched Quinap ligand, high enantioselection in the diboration can be achieved. The reaction is highly selective for trans- and trisubstituted alkenes and can be selective for some monosubstituted alkenes as well. The development of this reaction is described as is the substrate scope and experiments that are informative about the reaction mechanism and competing pathways.
• Biphilic Organophosphorus Catalysis: Regioselective Reductive Transposition of Allylic Bromides via P^III/P^VRedox Cycling

  We report that a regioselective reductive transposition of primary allylic bromides is catalyzed by a biphilic organophosphorus (phosphetane) catalyst. Spectroscopic, evidence supports the formation of a penta:coordinate (sigma(5)-P) hydridophosphorane as a key reactive intermediate. Kinetics experiments and computational modeling are consistent with a unimolecular docomposition of the sigma(5)-P hydridophosphorane via a conceited cyclic transition,structure that delivers the observed allylic transposition and completes a novel P-III/P-V redox Catalytic cycle. These results broaden the growing repertoire., of reactions catalyzed within the P-III/P-V redox couple and suggest additional opportunities for organophosphorus,catalysis in a biphilic mode.

  The design, synthesis, and evaluation of novel thieno[2,3-d]pyrimidin-4-yl hydrazone analogues as cyclin-dependent kinase 4 (CDK4) inhibitors are described. In continuing our program aim to search for potent CDK4 inhibitors, the introduction of a thiazole group at the hydrazone part has led to marked enhancement of chemical stability. Furthermore, by focusing on the optimization at the C-4' position
