It has been suggested that the sign of the circular dichroism (CD) maximum (C=O at 220-230 run) of the Y-lactones might be determined by the two factors. That is, configuration at C-2 (1) (2-(S)-configuration gave positive sign and 2-(R)-configuration gave negative sign) and the conformation of the

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
