• Direct Preparation of Heteroaromatic Compounds from Alkenes
  作者：Timothy Donohoe、Mikhail Kabeshov、Akshat Rathi、Ian Smith

  DOI：10.1055/s-0030-1259034

  日期：2010.12

  A series of aromatic heterocycles, thiazoles, imidazoles, and dimethoxyindoles, can be synthesised directly from alkenes via a ketoiodination-cyclisation protocol. The alkene starting materials are themselves easily accessible by many different and well-established approaches, and allow access to various aromatic heterocycles with excellent yields and regioselectivity.

  rocaglate skeleton. Trapping of the oxyallyl cation with a diverse range of nucleophiles has been used to generate over fifty novel amidino-rocaglate (ADR) and amino-rocaglate derivatives. Subsequently, these derivatives were evaluated for their ability to inhibit cap-dependent protein synthesis where they were found to outperform previous lead compounds including the rocaglate hydroxamate CR-1-31-B.

  Rocaglates 是从米兰属中分离出来的一类天然产物，具有高度取代的环戊[b]苯并呋喃骨架，可抑制帽子依赖性蛋白质合成。Rocaglalate 是一种颇具吸引力的化合物，因为它们具有通过特异性靶向真核起始因子 4A (eIF4A) 并干扰核糖体募集至 mRNA 来抑制体内肿瘤细胞维持的潜力。在本文中，我们描述了一种截获的逆纳扎罗夫反应，利用分子内甲苯磺酰迁移在罗卡格特骨架上生成反应性氧化烯丙基阳离子。用多种亲核试剂捕获氧烯丙基阳离子已被用来生成五十多种新型脒基罗卡酸盐 (ADR) 和氨基罗卡酸盐衍生物。随后，对这些衍生物抑制帽子依赖性蛋白质合成的能力进行了评估，结果发现它们优于以前的先导化合物，包括罗卡格酯异羟肟酸 CR-1-31-B。
• ‘Green' Synthesis of 2-Substituted 6-Hydroxy-[3H]-pyrimidin-4-ones and 4,6-Dichloropyrimidines: Improved Strategies and Mechanistic Study
  作者：Andreas Opitz、Werner Sulger、Ewald Daltrozzo、Rainer Koch

  DOI：10.1071/ch14073

  日期：——

  An improved route to 2-substituted 6-hydroxy-[3H]-pyrimidin-4-ones 4 and to 2-substituted 4,6-dichloropyrimidines 5 is reported. Without using highly toxic reactants, compounds 4 can be prepared conveniently in a one pot synthesis on a one mol scale with average yields up to 80 %. 4,6-Dichloropyrimidines 5, which are usually prepared in small quantities, are synthesized with average yields of 80 %

  一种改进的路线2-取代的6-羟基- [3 H ^ ] -嘧啶-4-酮4和2-取代的4,6-二氯嘧啶5报道。不使用剧毒反应物，就可以方便地在一锅合成中以1摩尔规模制备化合物4，平均收率可达80％。通常使用少量原料制备的4,6-二氯嘧啶5的平均收率为80％，最多可使用80 g起始原料。4氯化的机理是第一次进行计算研究。结果表明，磷酰氯的氯化反应以交替的磷酸化-氯化方式（途径1）进行，这比以两次磷酸化开始的顺序更可取。本文所述的研究的4，6-二氯嘧啶与二氯磷酸形成强络合物，但与盐酸形成弱络合物（在后处理期间生成）。后面这些配合物解释了在后处理过程中使用碳酸钠水溶液的必要性。为了防止在中间体或最终的二氯嘧啶和未反应的羟基嘧啶之间形成嘧啶鎓盐，可以用强酸（例如二氯磷酸）使后者失活，从而进行氯化反应，但阻止形成盐。
