Iridoids: The Revised Structure of Specionin

The revised structure of specionin has been proved by total synthesis; the key step involves a Norrish I type fragmentation of a norbornanone precursor.

IRIDOIDS: THE STRUCTURE ELUCIDATION OF SPECIONIN BASED ON CHEMICAL EVIDENCE AND 1H NMR ANALYSIS

The iridoid specionin is an effective antifeedant against the Eastern spruce budworm.Previous synthetic work has shown that the proposed structure was incorrect.Presently the total synthesis of the revised structure 2C is described.The structure elucidati
