✦ Synopsis

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 precursors. CH OR CH 131113 FH3 CH I 3 CH 3-CH=C -CH-CH-CH=C-CH2 -CH=CH-C=CH-CH2-pyr 13 12 11

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.
