We wish to report the structure of psilostachyin, I, a new sesquiterpene lactone from Ambrosia psilostachyia, and its synthesis from coronopilin, VIII. Hers and Hogenauer (1) previously established the structure of coronopilin, a sesquiterpene lactone isolated from 5. psilostachyia obtained in Kansa
A new sesquiterpene lactone called aquatolide was isolated from the hexane extract of Asteriscus aquaticus. Its constitution and stereochemistry were deduced from spectroscopic data, mainly homonuclear and heteronuclear two-dimensional NMR correlations. From the neutral part of a methanol deffated
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
