  Discovery of novel non-peptidic β-alanine piperazine amide derivatives and their optimization to achiral, easily accessible, potent and selective somatostatin sst1 receptor antagonists

  摘要：

  Structural simplification of the core moieties of obeline and ergoline somatostatin sst(1) receptor antagonists, followed by systematic optimization, led to the identification of novel, highly potent and selective sst(1) receptor antagonists. These achiral, non-peptidic compounds are easily prepared and show promising PK properties in rodents. (C) 2009 Elsevier Ltd. All rights reserved.

  Regioselective Dearomative Amidoximation of Nonactivated Arenes Enabled by Photohomolytic Cleavage of N‐nitrosamides

  摘要：

  摘要脱芳基螺环化反应是将烷烃转化为三维结构的一种很有前景的方法；然而，控制非活化烷烃脱芳基反应的区域选择性，以获得螺环化的 1,2-二官能度，而不是其动力学上偏好的 1,4-二官能度，却极具挑战性。在这里，我们揭示了一种新策略，即通过可见光直接诱导亚硝酰胺的 N-NO 键的均裂，实现（杂）烷的 1,2- 或 1,4- 氨基肟化，从而产生各种高区域选择性的氨基肟化螺环，而这些螺环以前是无法获得的，或者需要精心的合成工作。通过对照实验和密度泛函理论计算，研究了观察到的区域选择性的机理和起源。

  A new class of liquid polysiloxane materials obtainable from cost-effective commodity precursors allow tailoring a plurality of (multi)-functional properties. The materials are classified in terms of their chemical identity, which comprises Q-type non-organofunctional, T-type monoorganofunctional and optional D-type diorganofunctional moieties. The T-type organofunctional species within a polymeric MBB can be present in various preferred combinations defined by spatial, stereochemical and compositional factors. The corresponding method of production for the liquid polymeric polysiloxanes involves a scalable, non-hydrolytic acetic anhydride method either in a simple one-step format to create statistically distributed "core-only" hyperbranched poly-alkoxysiloxanes or as a two- or multistep process to create "core-shell" materials.
