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.
通过铑催化的联芳基连接的四炔与 1,4-二炔的双[2+2+2]环加成反应，实现了高度对映选择性的螺旋手性 1,1'-联三联苯的合成（高达 93%的对映体过量）。还研究了这些螺旋手性 1,1'-联三联苯的晶体结构和光物理性质。
