โฆ Synopsis
The elucidation of the structures of the cochliobolins A J, and B 2 has recently been reported 1,2 .
Inspection suggests that these substances are constructed from five isoprene units linked together head to tail, as shown in 2 for cochliobolin A.

Piericidins A(PA) and B(PB) are natural insecticidal substances isolated from mycellia of Streptomgces mobaraensis (l), and their structures have been elucidated as Ia and Ib, respectively (2,3). The novel structures prompted us to investigate the biosynthesis of these compounds using 14 C-labelled
Data are presented which shows that the llpoxlns are formed via a tetraene epoxlde. supportlng the asslgnment of the all trans tetraene geometry to llpoxin B.
