An I-2-promoted sp(3) C-H functionalization has been developed for the synthesis of 2,5-disubstituted oxazoles from easily available methyl ketones and benzylamines without any metal and peroxide catalyst. This domino oxidative cyclization process involves the cleavage of C H bond and the formation of C-N, C-O bonds. (C) 2012 Elsevier Ltd. All rights reserved.
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 dominooxidativecyclization from readily available starting materials under mild conditions.
开发了一种简便的单罐,无过渡金属的多米诺骨牌工艺,用于合成恶唑。因此,通过t- BuOOH / I 2介导的多米诺氧化环化反应可以容易地在温和条件下从容易获得的起始原料合成多种多取代的恶唑。
