biosynthetic orgin of the dichloroimine carbon in the stylotellanes A and B, (1) and (2), is defined by specific incorporation of sodium [14C] cyanide. Sodium [14C] thiocyanate is also involved in their biosynthesis. A mechanistic scheme is presented for the formation of these bioactive metabolites.

farnesyl isothiocyanate (2). A time course experiment with [(14)C]-cyanide revealed that the specific activity for farnesyl isothiocyanate decreases over time, but increases for stylotellane B (4), consistent with the rapid formation of farnesyl isothiocyanate (2) from inorganic precursors followed by a slower conversion to stylotellane B (4). The advanced precursors farnesyl isothiocyanate (2) and
