  Thermolysis of Benzoenyne−Allenes To Form Biradicals and Subsequent Intramolecular Trapping with a Tetraarylallene To Generate Two Triarylmethyl Radical Centers

  摘要：

  Thermolysis of the benzoenyne-allene 20 in 1,4-cyclohexadiene (1,4-CHD) at 75 degrees C produced the cycloaromatized adduct 23 in 22% yield. The reaction presumably proceeds through a cascade sequence involving an initial Myers cyclization reaction to form the biradical 21. The subsequent trapping of the aryl radical center in 21 with the tetraarylallenic moiety intramolecularly affords 22, having two stabilized triarylmethyl radical centers. Hydrogen-atom abstraction from 1,4-CHD by 22, manifesting its radical character, then produces 23. Similarly, thermolysis of benzoenyne-allenes 25 in 1,4-CHD furnished fluoranthenes 27 in essentially quantitative yields. The presence of the fused five-membered ring in 20 and 25 is necessary to direct the initial biradical-forming step toward the Myers cyclization reaction. Without the five-membered ring as in the cases of 31, the C2-C6 cyclization reaction became the preferred pathway, leading to benzofluorenes 34.

  摘要：

  未保护的联苯-2-羧酸可以在与羧酸盐相邻的位置用仲丁基锂完全金属化，然后可以进行位点选择性亲电取代。在 20–60 °C 的 THF 或苯中，正丁基锂和叔丁醇钾（LICKOR，3.5 当量）的超碱性混合物会攻击远程 C2' 位。所得二价阴离子环化得到芴酮骨架。还描述了联苯-3-和-4-羧酸的金属化反应。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)

  unclear. A medium throughput screen led to the identification of N-(2(-9H-carbazol-1-yl)phenyl)acetamide (GeA-69, 1) as a novel allosteric PARP14 MD2 (second MD of PARP14) inhibitor. We herein report medicinal chemistry around this novel chemotype to afford a sub-micromolar PARP14 MD2 inhibitor. This chemical series provides a novel starting point for further development of PARP14 chemical probes.

  聚腺苷二磷酸核糖聚合酶14（PARP14）已牵涉到DNA损伤反应途径中的同源重组。PARP14包含三个（ADP核糖结合）宏域（MD），尚不清楚其对病理学中整个PARP14功能的确切贡献。中等通量筛选导致鉴定出N-（2（-9H-咔唑-1-基）苯基）乙酰胺（GeA-69，1）作为新型变构PARP14 MD2（PARP14的第二个MD）抑制剂。我们在此报告了围绕这种新型化学型的药物化学，以提供亚微摩尔的PARP14 MD2抑制剂。该化学系列为进一步开发PARP14化学探针提供了新的起点。

  The metallation of aryl ketones was achieved by using LiTMP in the presence of ZnCl2·TMEDA, as evidenced by subsequent interception with iodine or by a palladium-catalysed cross-coupling reaction. One of the synthesized iodo ketones has been further elaborated to reach derivatives of biological interest.

  芳基酮的金属化是通过在ZnCl 2 ·TMEDA存在下使用LiTMP来实现的，随后通过碘的拦截或钯催化的交叉偶联反应证明了这一点。合成的碘代酮之一已被进一步精加工以达到具有生物学意义的衍生物。

  ortho-Substituted-2-biphenyl carboxylic acids of the type 3a–j were prepared by the tandem metalation sequence from 2-biphenyl carboxylic acid 1 with sec-butyllithium in THF at −78°C followed by quenching with electrophiles. The carboxylic acids 3a–f were converted into 1-substituted fluorenones 4a–f upon treatment with methanesulfonic acid.

  mechanism of the metalation of 2-biphenyl carboxylic acid (1) with the Lochmann-Schlosser superbase was determined by deuteriolysis. Both ortho (C(3)) and remote (C(2')) positions are metalated. The C(2')-metalated species 2 cyclizes instantaneously. Under suitable conditions, the doubly charged geminal dimetallo dialkoxide group C(OM)(2) 4 directs metalation in the adjacent position (C(1)), affording
