  Organic phosphorus compounds. 1. 4-(Benzothiazol-2-yl)benzylphosphonate as potent calcium antagonistic vasodilator

  摘要：

  A series of 4-(benzothiazol-2-yl)benzylphosphonic acid dialkyl ester derivatives were synthesized and evaluated for coronary vasodilatory activity by Langendorff's method in the isolated guinea pig heart. Many of the phosphonic acid dialkyl esters exhibited vasodilatory activity and calcium antagonism comparable with those of diltiazem hydrochloride, whereas phosphonic acid 1b and its nonphosphonated precursor 7a were inactive. These results indicate the necessity of the diethoxyphosphinyl moiety for vasodilatory activity. Substitution of the benzothiazole ring with a variety of substituents did not significantly enhance the activity of the unsubstituted compound. Compound 10b (KB-944) was chosen for detailed pharmacological evaluation.

• A Cross-Coupling Approach to Amide Bond Formation from Esters
  作者：Taoufik Ben Halima、Jaya Kishore Vandavasi、Mohanad Shkoor、Stephen G. Newman

  A palladium-catalyzed cross-coupling between aryl esters and anilines is reported, enabling access to diverse amides. The reaction takes place via activation of the C–O bond by oxidative addition with a Pd–NHC complex, which enables the use of relatively non-nucleophilic anilines that otherwise require stoichiometric activation with strong bases in order to react. High yields of aromatic, aliphatic

  据报道，钯催化的芳基酯和苯胺之间的交叉偶联，使得能够获得各种酰胺。反应是通过Pd-NHC络合物的氧化加成激活C-O键来进行的，这使得能够使用相对非亲核的苯胺，否则需要化学计量的活化才能使强碱发生反应。获得高产率的芳族，脂族和杂环产物。在存在和不存在催化剂的情况下评估了一系列活化酯，这表明催化方法大大增加了在不存在苛刻碱的情况下可用于酰胺键形成的亲电试剂的类型。

  procedure for glycosyl amides synthesis using selenocarboxylate as traceless reagent. Herein, we present a further application of selenocarboxylate-azide reaction for amide bond formation on a broader range of substrates, including heterocyclic systems and fatty acid. This method proved to be highly efficient for the synthesis of primary and secondary amides, sulfonamides, imides, phosphoramide and also

  我们最近报道了使用硒代羧酸盐作为无痕迹试剂的一锅法合成糖基酰胺的方法。在本文中，我们提出硒羧酸叠氮化物反应在更宽范围的底物（包括杂环系统和脂肪酸）上形成酰胺键的进一步应用。事实证明，该方法对于合成伯酰胺和仲酰胺，磺酰胺，酰亚胺，磷酰胺以及氨基甲酸酯非常有效。

  Herein we describe an alternative and unconventional approach of an aminocarbonylation reaction to access aryl amides from readily available and low-cost arylboronic acids and nitroarenes. Nickel metal can serve as both reductant and catalyst in this direct aminocarbonylation. This protocol exhibits a good functional group compatibility and allows a variety of aryl amides to be synthesized, including

  本文中，我们描述了一种氨基羰基化反应的替代性和非常规方法，可从容易获得的低成本芳基硼酸和硝基芳烃中获得芳基酰胺。在这种直接的氨基羰基化反应中，镍金属既可以充当还原剂，又可以充当催化剂。该方案显示出良好的官能团相容性，并允许合成多种芳基酰胺，包括几种药物样分子。
• DDQ-promoted direct transformation of benzyl hydrocarbons to amides via tandem reaction of the CDC reaction and Beckmann rearrangement

  An atom-efficient and transition metal-free approach to amides from the corresponding benzyl hydrocarbons through C–H and C–C bond cleavage has been developed. Mechanistic studies have shown that a DDQ-promoted cross-dehydrogenative coupling (CDC) reaction with subsequent oxidation and rearrangement are involved in this transformation.

  tris-azolium precursor 1 with palladium acetate under thermal conditions provided a CCC-pincer palladium(II) complex (2) bearing three NHCs (one imidazolylidene and two triazolylidenes) and one iodide ligand. Further treatment of complex 2 with an excess of AgSbF6 generates tris(carbene) dicationic palladium complex 3 in which the iodine ligands are exchanged with SbF6 anions and the metal center is stabilized

  在热条件下用乙酸钯处理三唑鎓前体1提供了带有三个 NHC（一个咪唑亚基和两个三唑基亚基）和一个碘化物配体的 CCC-钳状钯 (II) 复合物 ( 2 )。用过量的 AgSbF 6进一步处理配合物2生成三（卡宾）双阳离子钯配合物3，其中碘配体与 SbF 6阴离子交换，金属中心由一个乙腈配体稳定。配合物2和3在几个交叉偶联反应中进行了测试，显示在低催化剂负载和温和反应条件下的高转化率。此外，复合体2和3在末端炔烃的氢化硅烷化中表现良好，对E-异构体具有良好的选择性。
