Hydroxyl-assisted oxidative annulations of alkynes were accomplished with an inexpensive ruthenium(II) complex, delivering fluorescent pyrans via highly site selective as well as chemo- and regioselective C-H/O-H bond functionalizations.
羟基辅助炔烃的氧化环化反应可以用一种廉价的钌(II)配合物来实现,通过高度选择性的以及化学和区域选择性的 C-H/O-H 键官能化,得到荧光色吡喃。
