  An Enaminone-Directed Benzannulation/Macrocyclization Approach to Cyclophane Ring Systems

  摘要：

  A straightforward and modular preparative approach to 1,3,5-triaroylbenzene-based functionalized cyclophane ring systems has been developed. The key cyclophane-forming macrocyclization reaction was accomplished during the course of a regioselective cross-benzannulation between bis(aryl ethynyl) ketone and enaminone reactants. Macrocyclic products with ring sizes ranging from 18-to 22-membered were successfully constructed. The composition of the tether connecting the two aryl ethynyl ketone fragments can be easily varied; consequently, this method is suitable for construction of a diverse range of structurally distinct cyclophane products. To illustrate this feature, cyclophanes possessing xylyl, alkyl, di(ethylene triamine), and di(ethylene oxy) bridging units were synthesized in isolated yields of 11-46%. Three new cyclophanes (calixarene-like macrocyles 8 and 9, as well as crownophane 18) were structurally characterized by X-ray diffractometry.

  邻羰基辅助的金催化乙酸丙炔酯的区域选择性水合：获得α-酰氧基甲基酮和（±）-Actinopolymorphol B的合成†

  摘要：

  通过范围广泛的乙酸炔丙酯的区域选择性水合证明了合成α-酰氧基甲基酮的一般的原子经济方法。在二恶烷-H 2 O中包含1％Ph 3 PAuCl和1％AgSbF 6的现成催化剂可在短时间内在环境温度下在短短时间内有效地水解炔丙基乙酸酯的末端炔烃。如18所示，相邻的羰基可促进有效的区域选择性水化O标记研究。观察到功能部分的相容性和对各种酸不稳定的保护基的耐受性。催化条件也适合于进行TMS取代的炔丙基乙酸酯的水合作用，即使需要更长的反应时间才能完成。在水合过程中保留了炔丙基乙酸酯的立体完整性。通过以几乎定量的产量进行克规模的产品制备，成功地证明了该系统的鲁棒性。普通的α-酰氧基甲基酮被转化为1,2-二醇和1,2-氨基醇衍生物。肌动蛋白多酚B的合成首次实现，其中乙酸炔丙基酯的水合是关键步骤。

• Silver(I)-Catalyzed Reaction between Pyrazole and Propargyl Acetates: Stereoselective Synthesis of the Scorpionate Ligands (<i>E</i>)-Allyl-<i>gem</i>-dipyrazoles (ADPs)
  作者：M. Bhanuchandra、Malleswara Rao Kuram、Akhila K. Sahoo

  DOI：10.1021/jo401867e

  日期：2013.12.6

  The reaction between readily accessible pyrazole and propargyl acetates in the presence of Ag(I) catalyst yielded a new class of (E)-allyl-gem-dipyrazole scorpionate ligands: 1-aryl-2-N-pyrazolyl allyl acetates and 1,3-dipyrazolyl-3-arylpropene. The reaction showed broad substrate scope, and various functional and protecting groups were tolerated under the reaction conditions. The palladium(II) scorpionate complex could thus be easily prepared and successfully employed in Suzuki-Miyaura cross-couplings in water.
