✦ Synopsis

Abstract

Four novel types of iridals (compounds 8, 9, 15 and 16) have been isolated from lipid extracts of roots and rhizomes of I. pseudacorus and their structures (except the stereochemistry of 15 at C‐13 and C‐26 and of 16 at C‐13) elucidated by oxidative degradation combined with spectroscopic methods. They are up to now unknown triterpenoids with unusual spiro‐bicyclic structures. The possible biogenesis of these compounds is descussed.

The eremophilane group of sesquiterpenes is characterised by a carbon skeleton which does not obey the well-known isoprene rule, and although a number of examples have been discovered recently2 there are still relatively few known members of this group. We wish to
