The highly enantioselective synthesis of helically chiral 1,1'-bitriphenylenes has been achieved via rhodium-catalyzed double [2 + 2 + 2] cycloaddition of biaryl-linked tetraynes with 1,4-diynes (up to 93% ee). Crystal structures and photophysical properties of these helically chiral 1,1'-bitriphenylenes have also been studied.
螺旋手性 1,1'-亚联苯的高度对映选择性合成是通过铑催化的联芳基连接的四炔与 1,4-二炔(高达 93% ee)的双 [2 + 2 + 2] 环加成实现的。还研究了这些螺旋手性 1,1'-联苯的晶体结构和光物理特性。
