“…In 2015, our group disclosed agold-catalyzed formal [3+ +2] annulation between isoxazoles [5] and ynamides via presumable a-imino gold carbenes, [6a] which is both the first atomeconomical generation of a-imino metal carbenes through alkyne amination and the first reaction of isoxazoles with alkynes.O nt he basis of this,t he formal [5+ +2] and [4+ +2] annulations of isoxazoles with ynamides and ynol ethers were also achieved by employing platinum as the catalyst. [6b] After that, catalytic reactions of isoxazoles with alkynes have been extensively studied by Hashmi and co-workers, [7] Liu and coworkers, [8] and others, [9] and ag old-catalyzed formal [4+ +3] annulation of 3-en-1-ynamides with isoxazoles to form 4Hazepines via apresumable 6p electrocyclization has also been demonstrated by Liu and co-workers very recently. [8d] This strategy can not only lead to the divergent synthesis of arange of synthetically useful N-containing heterocycles,b ut also provide an efficient and atom-economical way for the N,Ofunctionalizations of alkynes.I ns pite of these efforts,t hese reactions have been mostly limited to noble-metal catalysts, and, to our knowledge,t he catalytic asymmetric reaction of isoxazoles with alkynes has not been reported to date.…”
