## Abstract Both 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 absolute conf

Vibrational-circular-dichroism (VCD) studies of the solution conformations of three 2,2'-substituted biphenyls are reported. Biphenyls with only two substituents at the peri-position normally show rotation about their central axis of chirality at room temperature in solution. We previously found no

Cruciferous phytoalexin related metabolites, (-)-dioxibrassinin ( ) and (-)-3-cyanomethyl-3-hydroxyoxindole (2) were prepared from isatin as racemates and were resolved by chiral HPLC. Their absolute configurations were determined by the new chiroptical technique, vibrational circular dichroism (VCD
