  Behavioral Treatment of Hypertensive Heart Disease in African Americans: Rationale and Design of a Randomized Controlled Trial

  摘要：

  African Americans experience higher morbidity, and mortality, than Whites do as a result of hypertension and associated cardiovascular disease. Chronic psychosocial stress has been considered an important contributing factor to these high rates. The authors describe the rationale and design for a planned randomized controlled trial comparing Transcendental Meditation, a stress-reduction technique, with lifestyle education in the treatment of hypertension and hypertensive heart disease in urban African Americans. They pretested 170 men and women aged 20 to 70 years over a 3-session baseline period, with posttests at 6 months. Outcomes included clinic and ambulatory blood pressure, quality, of life, left ventricular mass measured by, M-mode echocardiography, left ventricular diastolic function measured by Doppler and carotid atherosclerosis measured by fi-mode ultrasound. This trial was designed to evaluate the hypothesis that a selected stress reduction technique is effective in reducing hypertension and hypertensive heart disease in African Americans.

  自组装超分子胶囊内的亚胺催化：范围和机理研究

  摘要：

  尽管亚胺催化已成为有机化学中的重要工具，但它与超分子宿主系统的结合在很大程度上仍未得到探索。我们报告了对超分子宿主内亚胺催化的第一个例子的详细调查。在 α,β-不饱和醛的 1,4-还原的情况下，催化量的主体能够增加所形成产物的对映体过量。进行了几个对照实验，并提供了强有力的证据，证明对反应产物的对映体过量的调节确实源于胶囊内部的反应。研究了胶囊中增加的对映选择性的起源。此外，研究了底物和亲核试剂范围。动力学研究以及测得的动力学同位素效应证实，氢化物向底物的输送是胶囊内的速率决定步骤。苯并噻唑烷作为替代氢化物来源的探索揭示了氢化物来源本身的意外取代效应。所呈现的结果证实，超分子主体与亚胺催化的非共价组合正在开辟新的令人兴奋的可能性，以提高具有挑战性的反应中的对映选择性。

  The present invention provides a catalyst used for manufacturing an optically active carbonyl compound by selective asymmetric hydrogenation of an α,β-unsaturated carbonyl compound, which is insoluble in a reaction mixture, and a method for manufacturing the corresponding optically active carbonyl compound. Particularly, the invention provides a catalyst for obtaining an optically active citronellal useful as a flavor or fragrance, by selective asymmetric hydrogenation of citral, geranial or neral. The invention relates to a catalyst for asymmetric hydrogenation of an α,β-unsaturated carbonyl compound, which comprises: a powder of at least one metal selected from metals belonging to Group 8 to Group 10 of the Periodic Table, or a metal-supported substance in which the at least one metal is supported on a support; an optically active peptide compound; and an acid, and also relates to a method for manufacturing an optically active carbonyl compound using the same.

• Iminium Catalysis inside a Self-Assembled Supramolecular Capsule: Modulation of Enantiomeric Excess
  作者：Thomas M. Bräuer、Qi Zhang、Konrad Tiefenbacher

  DOI：10.1002/anie.201602382

  日期：2016.6.27

  The noncovalent combination of a supramolecular host with iminium organocatalysis is described. Due to cation–π interactions the reactive iminium species is held inside the host and reacts in this confined environment. The products formed differ up to 92 % ee from the control experiments without added host. A model rationalizing the observed difference is presented.

  Nonmetallic, chiral organic catalysts are used to catalyze the 1,4-hydride reduction of an α,β-unsaturated carbonyl compound. The α,β-unsaturated carbonyl compound may be an aldehyde or cyclic ketone, and the hydride donor may be a dihydropyridine. The reaction is enantioselective, and proceeds with a variety of hydride donors, catalysts, and substrates. The invention also provides compositions effective in carrying out the 1,4-hydride addition of α,β-unsaturated carbonyl compounds.

  The first enantioselective organocatalytic hydride reduction has been accomplished. The use of iminium catalysis has provided a new organocatalytic strategy for the enantioselective reduction of beta,beta-substituted alpha,beta-unsaturated aldehydes to generate beta-stereogenic aldehydes. The use of imidazolidinone 2 as the asymmetric catalyst has been found to mediate the transfer of hydrogen to a
