    摘要:
    钯催化的Mizoroki-Heck反应可以说是最近50年来发现的最重要的碳-碳键构筑反应之一,在化学生产中具有大量应用。这种获得诺贝尔奖的转化尚未克服其在一系列烷基亲电子试剂中,特别是具有可消除的β-氢原子的叔烷基卤化物普遍应用的障碍。尽管大多数钯催化的交叉偶联反应都是在热条件下利用钯配合物的基态反应性,并且通常应用单一配体体系,但我们报道钯催化的Heck反应在室温下能顺利进行,具有多种叔,仲,在双膦配体系统的存在下,用蓝色发光二极管辐照后,生成伯烷基溴和伯烷基溴。我们合理地认为,这种前所未有的转变是通过利用钯配合物的光激发态反应性来增强氧化加成并抑制不希望的β-氢化物消除而实现的。

    dual ligand effect and the irradiation effect in the catalytic cycle. The reaction is suggested to proceed via a hybrid alkyl Pd(I)-radical species generated by inner-sphere electron transfer of phosphine-coordinated Pd(0) species with alkyl bromide. This intriguing hybrid alkyl Pd(I)-radical species is elucidated by theoretical calculation to be a triplet species coordinated by three phosphine atoms
    我们在此报道,催化剂与双膦配体系统结合在蓝色发光二极管的温和辐照条件下催化具有广泛范围的叔,仲和伯烷基的甲硅烷基烯醇醚和烯酰胺的烷基化。该反应有效地递送α-烷基化的酮和α-烷基化的N-酰基酮亚胺,并且难以通过其他方法以立体选择性的方式制备后者。α-烷基化的N-酰基酮亚胺产物可以进一步用Hantzsch酯进行手性磷酸催化的不对称还原,以递送手性N-酰基保护的α-芳基化脂肪族胺具有高达99%ee的高对映体选择性,因此提供了一种简便合成手性α-芳基化脂肪族胺的方法,这在药物化学研究中具有重要意义。的Ñ -乙酰基酮亚胺产物也与各种类型的格氏试剂的顺利反应,得到空间庞大Ñ-乙酰基α-叔胺的收率高。理论研究与实验研究相结合,使人们对催化循环中双配体效应和辐射效应的反应机理有了了解。建议该反应通过由膦配位的Pd(0)物质与烷基的内球电子转移产生的杂化烷基Pd(I)-自由基物质进行。通过理论计算,这

    The present invention pertains to the discovery that B. anthracis possesses a luxS gene that encodes a functional LuxS polypeptide, and that B. anthracis synthesizes a functional AI-2 quorum-sensing molecule. The invention provides mutant B. anthracis bacteria lacking the function of the luxS gene, which do not produce a functional AI-2 molecule and have growth defects compared to wild-type B. anthracis . The invention also concerns methods for inhibiting the growth of B. anthracis , or for preventing or treating B. anthracis infection, by inhibiting the activity of the B. anthracis LuxS polypeptide, or by exposure of the B. anthracis to furanone. In particular, the invention concerns the use of furanone, a compound that inhibits AI-2-mediated quorum-sensing, to inhibit the growth of B. anthracis , to inhibit B. anthracis toxin production, particularly that of protective antigen, and to prevent or treat B. anthracis infection. The invention also provides methods to prevent B. anthracis infection, or enhance an immune response to B. anthracis infection, by administering a vaccine comprising a B. anthracis cell in which the luxS gene is mutated.
