Wucher, Philipp; Schwaderer, Judith B.; Mecking, Stefan published the artcile< Solid-Supported Single-Component Pd(II) Catalysts for Polar Monomer Insertion Copolymerization>, Computed Properties of 17100-64-0, the main research area is solid supported palladium catalyst preparation polar monomer insertion copolymerization; polystyrene supported methylpalladium sulfonatophenylphosphine complex preparation crystal mol structure; clay silica physisorbed methylpalladium sulfonatophenylphosphine complex preparation ethylene polymerization; montmorillonite clay supported methylpalladium sulfonatophenylphosphine complex preparation catalyst.

Heterogenized representatives of neutral phosphine sulfonato Pd(II) complexes for polar monomer insertion polymerization were prepared by two different approaches. [{κ2-(P,O)-(2-anisyl)2PC6H4SO2O}Pd(Me)L] (L = pyr, dmso, or Cl) complexes were physisorbed on inorganic substrates, namely, clay or silica. In addition, new phosphine sulfonato complexes bearing hydroxyl linker groups at the nonchelating P-aryl moiety were prepared These complexes were covalently tethered to cross-linked polystyrene. All immobilized palladium complexes are active in ethylene polymerization and ethylene/MA copolymerization without any addnl. cocatalyst. In addition, separation from the polymer solution formed and reutilization for another polymerization were demonstrated for polystyrene-bound complexes.

Canceill, Josette; Collet, Andre published the artcile< Synthesis and optical activity of p-(-)-2,7,12-tribromo-3,8,13-trihydroxycyclotribenzylene and related compounds. Evidence for the non-orthogonality of the B2u and B1u transitions in polysubstituted benzenes and its relevance to the exciton chirality method>, COA of Formula: C8H9BrO2, the main research area is cyclotribenzylene tribromotrihydroxy preparation configuration; trimerization cyclo benzenemethanol; benzenemethanol cyclotrimerization.

Cyclotrimerization of 4,3-Br(MeO)C6H3CH2OH gave 2,7,12-tribromo-3,8,13-trimethoxycyclotribenzylene (I, R = Me) and demethylation of the latter gave triphenol (±)-I (R = H) which was resolved into enantiomers. Methylation and acetylation of (+)- or (-)-I (R = H) furnished (+)- or (-)-I (R = Me, Ac). (-)-I were assigned P-(-) absolute configuration by chem. correlation with M-(+)-cyclotrianisylene. The optical activity of I was analyzed in the light of the exciton theory. In all compounds the exptl. exciton CD pattern in the 230 nm region, the B1u transition, was opposite to that expected from the spectroscopic moments of the substituents. This unexpected behavior suggested that the angle between the polarization directions of the B2u (290 nm) and B1u (230 nm) transitions in I should significantly depart from the value, 90°, usually assumed in polysubstituted benzenes, and emphasized the risk of using the B1u transition for configurational assignments based on chiroptical methods.

Xi, Junwei; Gu, Zhenhua published the artcile< Palladium-Catalzyed Atroposelective 16-Membered Macrocyclization: Total Synthesis of Isoplagiochin D†l>, Synthetic Route of 17100-64-0, the main research area is isoplagiochin D total synthesis atroposelective macrocyclization palladium catalyst WingPhos.

Isoplagiochin D (I) is a ring-strained macrocyclic bisbibenzyl, which shows stable axial chirality in one biaryl structure, and semistable axial chirality in the other biaryl moiety. We report here an unprecedented example for the catalytically asym. synthesis of ring-strained atropisomers via Pd-catalyzed macrocyclization between benzyl halides and carbenes. This newly developed Pd-catalyzed asym. macrocyclization protocol enabled a quick synthesis of isoplagiochin D in a highly enantioselective manner.

Zhang, Qin; Zhong, Ying; Yan, Lin-Na; Sun, Xun; Gong, Tao; Zhang, Zhi-Rong published the artcile< Synthesis and preliminary evaluation of curcumin analogues as cytotoxic agents>, Synthetic Route of 17100-64-0, the main research area is curcumin derivative preparation SAR anticancer cytotoxicity.

A series of curcumin analogs with different substituents at the 4-position of the Ph group were synthesized and screened for in vitro cytotoxicity against a panel of human cancer cell lines. Several novel curcumin analogs, especially I and II, exhibited selective and potent cytotoxic activity against human epidermoid carcinoma cell line A-431 and human glioblastoma cell line U-251, implying their specific potential in the chemoprevention and chemotherapy of skin cancer and glioma. The preliminary SAR information extracted from the results suggested that introduction of appropriate substituents to the 4′-positions could be a promising approach for the development of new cytotoxic curcumin analogs with special selectivity for A-431 and U-251 cell lines.
