Abstract
Victorins are cyclic pentapeptide natural products isolated from the fungus Cochliobus victoriae. Using a combination of synthesis and spectroscopic methods we have assigned the geometry of the vinyl chloride residue and determined the stereochemistry of the 5,5-dichloroleucine moiety.
Key words
amino acids - halogenation - natural products - spectroscopy - stereoselective synthesis

The optical rotation has not been reported for 5,5-dichloroleucine isolated following degradation of the victorins,¹,² hence the absolute stereochemistry is assumed from the earlier reported ORD shifts of the 2,4-DNP derivatives.²
