  Nonspecific Medium Effects versus Specific Group Positioning in the Antibody and Albumin Catalysis of the Base-Promoted Ring-Opening Reactions of Benzisoxazoles

  摘要：

  The mechanisms by which solvents, antibodies, and albumins influence the rates of base-catalyzed reactions of benzisoxazoles have been explored theoretically. New experimental data on substituent effects and rates of reactions in several solvents, in an antibody, and in an albumin are reported. Quantum mechanical calculations were carried out for the reactions in water and acetonitrile, and docking of the transition state into a homology model of antibody 34E4 and an X-ray structure of human serum albumin was accomplished. A microenvironment made up of catalytic polar groups (glutamate in antibody 34E4 and lysine in human serum albumin) surrounded by relatively nonpolar groups is present in both catalytic proteins.

  通过邻位取代苯胺与CO 2 / H 2的环化反应，钴催化合成含氮杂环

  摘要：

  从绿色和可持续的化学观点来看，涉及CO 2的化学合成具有重要意义。本文中，我们报道了由CoF 2，CsF和P（CH 2 CH 2 PPh 2）3（表示为P P 3）组成的非贵金属催化体系，用于由邻位取代的苯胺和CO合成含氮杂环2 / H 2。机理研究表明[Co（P P 3）H（CO 2）] +是在工作条件下具有催化活性的中间体；CsF和CsF在通过氢键相互作用活化邻位取代的苯胺中起重要作用，从而促进最终产物的形成。该催化体系是高效的，并且允许宽范围的邻位取代的苯胺，以及优异的官能团耐受性，以良好至优异的产率提供各种含氮杂环。

  Molecules labeled with fluorine-18 (18F) are used in positron emission tomography to visualize, characterize and measure biological processes in the body. Despite recent advances in the incorporation of 18F onto arenes, the development of general and efficient approaches to label radioligands necessary for drug discovery programs remains a significant task. This full account describes a derisking approach
