  Transformation of N,N-diisopropylarylmethylamines into N-isopropylarylmethylamines with molecular iodine

  摘要：

  N,N-Diisopropylarylmethylamines were smoothly converted into the corresponding N-isopropylaryl-methylamines by the reaction with molecular iodine in the presence of Na2CO3 in chloroform at 60 degrees C. Other related tertiary amines were also transformed into the corresponding secondary amines by the reaction with molecular iodine under the same reaction conditions. (C) 2015 Elsevier Ltd.

  用于硅烷还原酰胺的BEt 3基催化剂

  摘要：

  本文报道了一种简单但实用的催化体系的开发，该体系用于用氢硅烷或氢硅氧烷选择性还原酰胺。发现低成本且易于获得的三乙基硼烷（在THF中为1.0 M）与催化量的碱金属碱结合，可催化所有三种酰胺类别（叔，仲和伯酰胺）的还原反应，从而在室温下形成胺。温和的条件。另外，还可以通过使用BEt 3和碱的适当组合来实现将仲酰胺选择性转化为醛亚胺和将伯酰胺选择性转化为腈。这些赌注3的范围碱催化的酰胺氢化硅烷化反应已被深入研究。机理研究的初步结果表明，经过改进的Piers硅烷Si–H···B活化方式，其中BEt 3提取氢化物的过程是通过烷氧基或氢氧根阴离子与Si中心的配位来促进的。

  Unsymmetrical cyanine dyes that incorporate an aza-benzazolium ring moiety are described, including cyanine dyes substituted by a cationic side chain, monomeric and dimeric cyanine dyes, chemically reactive cyanine dyes, and conjugates of cyanine dyes. The subject dyes are virtually non-fluorescent when diluted in aqueous solution, but exhibit bright fluorescence when associated with nucleic acid polymers such as DNA or RNA, or when associated with detergent-complexed proteins. A variety of applications are described for detection and quantitation of nucleic acids and detergent-complexed proteins in a variety of samples, including solutions, electrophoretic gels, cells, and microorganisms.

  Compounds that exhibit aggregation induced emission (AIE), and more particularly to water-soluble conjugated polyene compounds that exhibit aggregation induced emission. The conjugated polyene compounds can be used as bioprobes for DNA detection, G-quadruplex identification, and potassium-ion sensing. The polyenes also can be utilized as an external fluorescent marker to study conformational structures, to monitor folding processes of label-free oligonucleotides with G-rich strand sequences, and to visualize DNA bands in PAGE assay. The polyenes have applications in high-throughput anticancer drug screening and are useful for the development of efficient anti-cancer drugs. Furthermore, the present subject matter can also be used to monitor fibrillation of amyloid proteins and to facilitate the storage and delivery thereof.

  Reduction of a wide range of tertiary amides with 2 molar equivalents of diphenylsilane was promoted by 0.1 mol% of RhH(CO)(PPh3)3 at room temperature, affording the corresponding tertiary amines in high yields. The synthetic utility is demonstrated by chemoselective reductions of amides having functional groups such as ester and epoxy groups which are not tolerated by the conventional reductions with
