SYNTHESIS OF THE RACEMIC AND OPTICALLY ACTIVE FORMS OF GIZZEROSINE, THE INDUCER OF GIZZARD EROSION IN CHICKS
The racemate end both the (R)- and (S)-forms of gizzerosine were synthesised, and the (S)-isomer was identified as the toxic substance in fish meal causing severe gizzard erosion (black vomit) in chicks.
