Remarkable incorporation of the first sulfur containing indole derivative: another piece in the biosynthetic puzzle of crucifer phytoalexins

The first sulfur labelled compound, [H-2(4),S-34]indolyl-3-acetothiohydroxamic acid, is incorporated into the phytoalexins cyclobrassinin and spirobrassinin and the indole glucosinolate glucobrassicin, indicating that both biosynthetic pathways are closely related.
