enantiomers of an optically active trialkynyl(phenyl)-methane (the key building blocks in the construction of a stable expanded cubane) have been prepared. The strategy involved the resolution of a racemic intermediate by means of HPLC on a chiral stationary phase. The absoluteconfiguration of this intermediate was unambiguously assigned by using vibrational circular dichroism (VCD) and optical rotatory dispersion
