  两亲性超支化聚乙氧基硅氧烷：一种自模板组装平台，用于制备功能性介孔结构二氧化硅，用于水对映选择性反应

  摘要：

  作为非均相催化剂的两亲介观结构的二氧化硅的制备由于其在水中的高度分散性而有利于促进水反应。在这项工作中，通过利用自模板组装策略的优势，我们通过使用两亲性聚（乙二醇）单甲醚改性的超支化聚乙氧基硅氧烷作为二氧化硅前体。如研究中所述，手性钌/二胺官能化催化剂在水中将无环α-三氟甲基亚胺进行不对称转移氢化成手性α-三氟甲胺，而手性方酰胺功能化的催化剂能够将乙酰丙酮高效不对称地迈克尔加成到盐水中的硝基烯烃上。两种高催化性能均归因于明确定义的单中心手性活性物种，高度分散的催化中心和实用的相转移功能的组合多功能性。此外，两种催化剂也可以容易地回收并重复使用至少七次而不会损失催化活性。这样的特征使得该自模板组件对于构造各种非均相催化剂具有吸引力。和实用的相转移功能。此外，两种催化剂也可以容易地回收并重复使用至少七次而不会损失催化活性。这样的特征使得该自模板组件对于构造各种非均相催化剂具有吸引力。和实用的相

  Acyclic amides as estrogen receptor ligands: Synthesis, binding, activity and receptor interaction

  摘要：

  We have prepared a series of bisphenolic amides that mimic bibenzyl and homobibenzyl motifs commonly found as substructures in ligands for the estrogen receptor (ER). Representative members were prepared from three classes: N-phenyl benzamides, N-phenyl acetamides, and N-benzyl benzamides; in some cases the corresponding thiocarboxamides and sulfonamides were also prepared. Of these three classes, the N-phenyl benzamides had the highest affinity for ER, the N-phenyl acetamides had lower, and the N-benzyl benzamides were prone to fragmentation via a quinone methide intermediate. In the N-phenyl benzamide series, the highest affinity analogues had bulky N-substituents; a CF3 group, in particular, conferred high affinity. The thiocarboxamides bound better than the corresponding carboxamides and these bound better than the corresponding sulfonamides. Binding affinity comparisons suggest that the p-hydroxy group on the benzoate ring, which contributes most to the binding, is playing the role of the phenolic hydroxyl of estradiol. Computational studies and NMR and X-ray crystallographic analysis indicate that the two anilide systems studied have a strong preference for the s-cis or exo amide conformation, which places the two aromatic rings in a syn orientation. We used this structural template. together with the X-ray structure of the ER ligand binding domain, to elaborate an additional hydrogen bonding site on a benzamide system that elevated receptor binding further. When assayed on the individual ER subtypes, ER alpha and ER beta, these compounds show modest binding affinity preference for ER alpha. In a reporter gene transfection assay of transcriptional activity, the amides generally have full to nearly full agonist character on ERa, but have moderate to full antagonist character on ER beta. One high affinity carboxamide is 500-fold more potent as an agonist on ER alpha than on ER beta. This work illustrates that ER ligands having simple amide core structures can be readily prepared, but that high affinity binding requires an appropriate distribution of bulk, polarity, and functionality. The strong conformational preference of the core anilide function in all of these ligands defines a rather rigid geometry for further structural and functional expansion of these series.

  In recent years, H2 activation at non‐transition‐metal centers has met with increasing attention. Here, a system in which H2 is activated and transferred to aldimines and ketimines using substoichiometric amounts of lithium bis(trimethylsilyl)amide is reported. Notably, the reaction tolerates the presence of acidic protons in the α‐position. Mechanistic investigations indicated that the reaction proceeds

  Addition of diethyl lithiodifluoromethylphosphonate to N-substituted imines provides N-substituted α,α-difluoro-β-aminophosphonates. N-Alkyl, aryl, or Boc substituted aldimines give good to high yields in these reactions, while in ketimine series, only activated N-(2,2,2-trifluoro-1-phenylethylidene)aniline showed high reactivity.
