  Substituted oxazole benzenesulfonamides as potent human β3 adrenergic receptor agonists

  摘要：

  As a part of our investigation into the development of orally bioavailable beta(3) adrenergic receptor agonists, we have identified a series of substituted oxazole derivatives that are potent beta(3) agonists with excellent selectivity against other beta receptors. Several of these compounds showed excellent oral bioavailability in dogs. One example, cyclopentylethyloxazole 5f is a potent beta(3) agonist (EC50 = 14 nM, 84% activation) with 340-fold and 160-fold selectivity over beta(1) and beta(2) receptors, respectively, and has 38% oral bioavailability in dogs.

  A fragment‐assembling strategy is used to form oxazoles from aryl acetaldehydes, amines, and molecular oxygen under mild conditions (see scheme). The transformation is highly efficient with the removal of six hydrogen atoms, including the cleavage of four C(sp3)H bonds.

  片段组装策略用于在温和条件下由芳基乙醛，胺和分子氧形成恶唑（请参阅方案）。通过去除六个氢原子，包括四个C（sp 3）H键的裂解，该转化过程非常高效。
