A novel and straightforward intramolecular cyclization of glycine derivatives to 2-substituted benzoxazoles through copper-catalyzed oxidative C–H/O–H cross-coupling was described. A variety of glycine derivatives involving short peptides underwent cross-dehydrogenative-coupling readily to afford diverse 2-substituted benzoxazoles. The synthetic method has the advantages of simple operation, broad

The invention provides antimicrobial agents and methods of using the agents for sterilization, sanitation, antisepsis, disinfection, and treatment of infections in mammals.
Herein, an atom-economical and eco-friendly electrochemical oxidation/cyclization of glycinederivatives through intramolecular Shono-type oxidative coupling is disclosed, leading to a variety of 2-substituted benzoxazoles in 51–85% yields. This oxidative cyclization proceeded in transition metal- and oxidant-free conditions and generated H2 as only a byproduct. Additionally, gram-scale reactions and
在此,公开了一种通过分子内 Shono 型氧化偶联对甘氨酸衍生物进行原子经济且环保的电化学氧化/环化,从而以 51-85% 的收率生成多种 2-取代苯并恶唑。这种氧化环化在无过渡金属和无氧化剂的条件下进行,并产生 H 2作为副产物。此外,克级反应和广泛的底物范围证明了该协议的合成有用性。
