Ir催化的四炔或辛炔与单炔的对映选择性[2 + 2 + 2]环加成反应得到了螺旋手性quinquearyl和noviaryl化合物，它们分别具有4个和8个连续的轴向手性，几乎是对映体纯的形式。
Ir-catalyzed enantioselective [2 + 2 + 2] cycloaddition of tetraynes or an octayne with monoalkynes proceeded to give helically-chiral quinquearyl and noviaryl compounds, which respectively have four and eight consecutive axial chiralities, in an almost enantiomerically pure form.
