  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.

  An efficient synthesis of 2,5-disubstituted oxazoles via Co(III) catalysis is described herein. The synthesis is achieved under mild conditions through [3+2] cycloaddition of N-pivaloyloxyamides and alkynes. The reaction operates through an internal oxidation pathway and features a very broad substrate scope. The one-step synthesis of natural products such as texamine and balsoxin has been demonstrated

  A facile type of one-pot, transition-metal-free domino process was developed for the synthesis of oxazoles. Thus, a variety of polysubstituted oxazoles were easily synthesized via t-BuOOH/I2-mediated domino oxidative cyclization from readily available starting materials under mild conditions.
