  对映选择性碳级联反应：环戊二烯的有效方法及其在Diels-Alder反应中的应用

  摘要：

  提出了一种不对称卡宾级联反应，该反应通过卡宾/炔烃复分解和形式（3 + 2）环加成反应进行，并将炔基连接的烯醇重氮乙酸酯转化为手性双环环戊二烯。并且迄今尚未公开这些卡宾级联转化的催化不对称形式。在机理研究中观察到了环丙烯中间体的质子信号，清楚地表明了反应途径。此外，这些产物通过Diels-Alder反应被拦截，从而以高收率和对映选择性提供桥连的多环结构。

• Bioisosteric replacement of an acylureido moiety attached to an indolin-2-one scaffold with a malonamido or a 2/4-pyridinoylamido moiety produces a selectively potent Aurora-B inhibitor

  Bioisosteric replacement of acylureido moiety in 6-acylureido-3-pyrrolylmethylidene-2-oxoindoline derivatives resulted in a series of malonamido derivatives with indolin-2-one scaffold (11-14). Further conformational restrictions of the malonamido moiety led to 2-oxo-1,2-dihydropyridine (21-25) or a 4-oxo-1,4-dihydropyridine derivatives (31-36). 4-Oxo-1,4-dihydropyridine derivatives were more potent Aurora B inhibitors than their 2-oxo-1,2-dihydropyridine counterparts and demonstrated cytotoxicities against A549 and HepG2 cells in the submicromolar range. In A549 cells, 31h decreased phosphorylation of histone H3, triggered polyploidy, induced expression of pro-apoptotic Fas and FasL with subsequent activation of caspase 8, resulting into apoptosis. In a Huh7-xenograft mouse model, 31h demonstrated potent in vivo efficacy with a daily dose of 5 mg/kg.
• A Pyrazole to Furan Rearrangement. Thermolysis of 5-Azido-4-formylpyrazoles

  5-Azido-3-benzyl-4-formyl-1-phenylpyrazoles 1a-c extrude dinitrogen upon heating in toluene to give the corresponding nitrenes, which immediately rearrange via a new ring-opening ring-closure reaction to produce an equimolar mixture of 4-cyano-2-phenyl-3-phenylazofurans 2a-c and 3-benzyl-4-cyano-1-phenylpyrazoles 3a-c. The formation of the 4-cyano-2-phenyl-3-phenylazofurans 2a-c is the first example in the pyrazole series of a nitrene rearrangement, in which the parent heterocyclic system of the product differs from that of the starting material. The isolation of equimolar amounts of the two products points to the fact that their formation occurs by two mechanistically interconnected pathways, between which the exchange of a redox equivalent takes place. Evidence for the existence of two mechanistically interlinked pathways is presented, and the insight into the stoechiometry of the reaction is taken advantage of to optimize the reaction with respect to either of the two products 2 or 3. Thus, it is demonstrated how one can bias the two pathways using external reagents, thereby changing the product distribution ratio 2:3 from 1:1 in the unbiased case, to 1:4 in one direction, and to better than 20:1 in the other direction.
