  A Mild and Selective Method for the Catalytic Hydrodeoxygenation of Cyanurate Activated Phenols in Multiphasic Continuous Flow

  摘要：

  sA low-energy, high-selectivity approach to the catalytic hydrodeoxygenation of phenols is reported using batch or continuous flow methods to react 3 equiv of phenol with cyanuric chloride then hydrogenolyzing the triarylcyanurate intermediate to give 3 equiv of deoxo aromatic. The use of cyanuric chloride compares favorably with existing activation methods, showing improved scalability, atom efficiency, and economics. The scope of both the activation and hydrogenolysis stages are explored using lignin-related phenols. Initial development has identified that continuous stir tank reactors (CSTRs) enable a multiphasic process for converting guaiacol to anisole and at steady state overcome the catalyst deactivation issues observed in batch, seemingly caused by the cyanurate byproduct. Green chemistry aspects and the potential for industrial adoption are discussed.

  The new analogue 2 of combretastatin A-4 was discovered to be an inhibitor of tubulin polymerization with an IC50 of 7.6 microM and reduced angiogenesis in the in vivo chick embryo model. Interestingly, in a series of 2,3-diarylmaleimides closely related to this lead, no other compound was found to be active in the tubulin polymerization assay. However, by screening in the in vivo chick embryo assay

  发现康美他汀A-4的新类似物2是微管蛋白聚合的抑制剂，在体内鸡胚模型中的IC50为7.6 microM，并减少了血管生成。有趣的是，在一系列与该铅紧密相关的2，3-二芳基马来酰亚胺中，在微管蛋白聚合测定中未发现其他化合物具有活性。然而，通过在体内进行筛选，将雏鸡胚胎测定法10鉴定为有效的血管生成抑制剂，表明了另一种靶标。确实，分子建模研究表明在模型激酶CDK2的ATP结合位点有一个合理的10结合模式。根据这些结果，在10种类似的12种蛋白激酶中筛选了10种类似物的抑制活性，发现10种对VEGF-R2的高亲和力表明IC50为2.5 nM。

  Total synthesis of cytotoxic marine alkaloids, lamellarins D, L, and N, has been achieved by using Hinsberg-type pyrrole synthesis and palladium-catalyzed Suzuki–Miyaura coupling of the 3,4-dihydroxypyrrole bistriflate 6 as the key reactions. The total yields of lamellarins D, L, and N from the common intermediate 6 are 54, 58, and 50%, respectively.

  reactivity for C-N cross-coupling reactions is reported. This catalyst system enables the use of aryl mesylates as a coupling partner in C-N bond-forming reactions. Additionally, the use of BrettPhos permits the highly selective monoarylation of an array of primary aliphatic amines and anilines at low catalyst loadings and with fast reaction times, including the first monoarylation of methylamine.

  A new class of easily accessible hemilabile benzimidazolyl phosphine ligands has been developed. The ligand skeleton is prepared from commercially available and inexpensive o-phenylenediamine and 2-bromobenzoic acid. With catalyst loading down to 0.5 mol% palladium, excellent catalytic activity towards the Suzuki-Miyaura coupling of aryl mesylates is still observed. This represents the lowest catalyst

  The present invention provides an activator in arylamination using a palladium compound as a catalyst, which is superior to conventional phosphines in stability and performance. With the phosphine sulfide as an activator, an arylamination reaction achieves improved selectivity to produce a desired aromatic amine in an obviously increased yield as compared with a reaction using the corresponding phosphine compound. Moreover, the phosphine sulfide of the invention is impervious to oxidation and exists stably in air and therefore sufficiently withstands use on an industrial scale.
