  名称：

  cis–trans Enantiomerism in the Diels–Alder cycloadducts of 6-arylfulvenes with maleic anhydride: resolution of the exo adducts via the N-((1S)-1-(naphth-1-yl)ethyl)imide derivatives: assignment of the absolute configurations based on the crystal structure of an imide diastereomer

  摘要：

  A new case of the uncommon cis-trans enantiomerism is presented. The titled anhydride adducts were prepared in good yields by the known reaction of three 6-arylfulvenes with maleic anhydride (aryl = phenyl, p-tolyl and p-anisyl). The exo adducts were converted to the corresponding imides by reaction with (1S)-1-(naphth-1-yl)ethylamine in similar to 80% yields, and the resulting diastereomeric imides separated by silica gel column chromatography. They were hydrolysed and recyclised to the chiral anhydrides, in 'one-pot' with 10% NaOH-EtOH, followed by treatment with 2 M HCl, in similar to 40% yields. The titled anhydrides were thus obtained in homochiral form, in enantiomeric purities (generally) of similar to 90% as indicated by chiral HPLC. The chiral anhydrides were also converted to the corresponding imides (presumably stereospecifically), by treatment with ammonia solution in excellent yields. The crystal structure of one of the above diastereomeric imides (derived from 6-phenylfulvene) was determined, and based on the known (S)-configuration of the naphthylethylamine moiety, the 'configurations' of the original anhydride adducts were assigned.

  selected ferrocene derivatives were determined by X-ray diffraction analysis. The ferrocene derivatives and the ruthenium complexes were tested in vitro for their cytotoxic properties against three cell lines derived from ovarian cancer (A2780, A2780cis, and SK-OV-3) and against non-tumour embryonic cell line HEK293 (human kidney cells). The most active ferrocene derivatives displayed cytotoxicity in submicromolar

  applicable chiral Cp ligand collection (JasCp ligands) with highly variable and adjustable structures. Their modular nature and their amenability to rapid structure variation enabled the efficient discovery of ligands for three enantioselective RhIII‐catalyzed C−H activation reactions, including one unprecedented transformation. This novel approach should enable the discovery of efficient chiral Cp ligands

  环戊二烯基（Cp）配体可有效控制各种过渡金属催化的转化，特别是对映选择性的CH活化。目前只有几种手性Cp配体可用。因此，用于手性Cp配体发现的概念上通用的方法将是无价的，因为它将使得能够发现适用的Cp配体并有效且快速地改变和调节其结构。在这里，我们描述了具有高度可变和可调节结构的结构多样且广泛适用的手性Cp配体集合（JasCp配体）的三步克级合成。它们的模块性质和对快速结构变化的适应性使得能够有效发现三种对映选择性Rh III的配体催化的CH活化反应，包括一种前所未有的转化。这种新颖的方法应该能够发现用于各种进一步对映选择性转化的有效手性Cp配体。

  The described titanium‐catalyzed hydroalumination of conjugated dienes opens up a new way to allylaluminium reagents. The reaction is carried out by using diisobutylaluminium hydride (DIBAL‐H) and a catalytic amount of [Cp2TiCl2] (Cp=cyclopentadienyl). When applied to mono‐ and disubstitued pentafulvenes, this reaction proceeds in a highly endocyclic manner. The formed allylaluminium compounds react

  The catalytic enantioselective [2+2] cycloaddition between quinones and fulvenes was achieved, for the first time, by the use of a chiral copper(II) complex catalyst. The transformation afforded a series of enantiomerically enriched [6,4,5]-tricyclic cyclobutane derivatives in good yields with excellent regio- and stereoselectivities. Furthermore, the [2+2] adducts could be easily converted into formal
