Abstract

The chiral Rh complex catalyzes the consecutive [2+2+2] cycloadditions, whereas the chiral neutral Ir complex causes a single [2 + 2 + 2] cycloaddition.

## Abstract Enantioselective intramolecular cycloaddition of hexaynes with 1,3‐diyne moiety was examined. Chiral Rh catalyst provided axially chiral 1,1′ ‐bis(biphenylenyl) derivatives by consecutive [2+2+2] cycloaddition. In contrast, chiral Ir catalyst provided axially chiral macrocyclic compound
