  Synthesis and Evaluation of Potent and Selective β₃ Adrenergic Receptor Agonists Containing Acylsulfonamide, Sulfonylsulfonamide, and Sulfonylurea Carboxylic Acid Isosteres

  摘要：

  Starting from phenethanolamine aniline leads 3a and 3b, we have identified a series of functionally potent and selective beta(3) adrenergic receptor (AR) agonists containing acylsulfonamide, sulfonylsulfonamide, or sulfonylurea groups within the aniline phenethanolamine series. In beta(3) beta(2), and beta(1) AR cAMP functional assays, 3a and other right-hand side (RHS) carboxylate analogues were found to be full agonists that were modestly selective against beta(1) or beta(2) ARs, while analogues lacking RHS acid functionality were active at beta(3) AR but not selective. Replacement of the carboxylate with acylthiazole and acylmethylsulfone gave potent, but only modestly selective, compounds. Increasing the size of the RHS sulfonamide substituent with phenyl or p-toluene afforded compounds with good potency and functional selectivity (beta(3) AR pEC(50) greater than 8; beta(1) and beta(2) AR selectivity greater than 40- and 500-fold, respectively). Our SAR studies suggest that the potency and selectivity profile of the best analogues reported here is a result of both the steric bulk and acidity of the RHS sulfonamide NH group. Although all of the analogues had a pharmacokinetic half-life of less than 2 h, acylsulfonamides 43 and 44 did show moderately low clearance in dogs. These two compounds were further evaluated by thermographic imaging in mice and were found to produce a robust thermogenic response via oral administration.

  对映选择性铁催化的 O-H 键插入

  摘要：

  铁的易得性、低廉的价格和环境友好的特性意味着它是催化中贵金属的理想替代品。最近报道的铁催化反应数量的增长反映了对可持续化学的需求不断增加。仅报道了有限数量的手性铁催化剂，并且通常证明这些手性铁催化剂的对映选择性低于其他过渡金属催化剂，因此限制了它们的吸引力。在这里，我们报告螺-双恶唑啉配体的铁配合物是不对称 O-H 键插入反应的高效催化剂。这些配合物催化插入各种醇甚至水的 O-H 键，在温和的反应条件下具有出色的对映选择性。选择性超过了用其他过渡金属催化剂获得的选择性。

  日期：2017.8.18

  A new continuous flow protocol for the diazotization of methylamine with 1,3-propanedinitrite in THF is reported. The synthesis of methyl esters was achieved in high yields from a variety of carboxylic acids in 20 min at 90 °C. Additionally, this protocol was extended to other aryl and alkyl amines, namely secondary amines, to produce various substituted esters in high yield using 2-MeTHF as a solvent

  报道了一种新的连续流方案，用于在THF中将甲胺与1,3-丙炔重氮化。在90°C下20分钟内可以从多种羧酸中高收率地合成甲酯。另外，该方案扩展到其他芳基和烷基胺，即仲胺，以使用2-MeTHF作为溶剂以高收率生产各种取代的酯。反应条件与许多官能团相容，即含氮杂环，炔烃，烯烃，醇和酚。机理研究表明，反应似乎是通过瞬态重氮物质而不是重氮中间体进行的。
