Ptaquiloside Z, a new toxic unstable sesquiterpene glucoside from the neotropical bracken fern Pteridium aquilinum var. caudatum

Reversed-phase HPLC fractionation, monitored by brine shrimp bioassay, led to the isolation of a new illudane-type sesquiterpene glucoside, ptaquiloside Z (2), as well as the known bracken carcinogen ptaquiloside (1), from a bioactive aqueous extract of the neotropical bracken fern Pteridium aquilinum var. caudatum (Pteridaceae). The structure of ptaquiloside Z (2) was confirmed by spectroscopic analyses and chemical degradation. Both compounds exhibited similar toxicity (LC50 62.5μg/ml at 24h and LC50 7.8μg/ml at 48h) toward brine shrimp. Copyright (C) 1997 Elsevier Science Ltd.
RHODIUM CATALYSED SYNTHESIS OF ILLUDALANES
Neeson, S. J.,Stevenson, P. J.
, p. 6239 - 6248 (1989)
A short, regiospecific route to pterosin Z and calomelanolactone is presented in which the key step is a rhodium catalysed intramolecular cycloaddition.
Synthesis and antispasmodic activity of nature identical substituted indanes and analogues

The synthesis of a series of substituted indanes which provide routes to nature-identical compounds and their analogues is reported. The smooth muscle relaxant activity of a series of substituted indanes and indanones together with their analogues has been measured. A compound with significant smooth muscle relaxant activity has been identified.
