Gathering together the widespread literature in the field, this monograph acts as a reference
guide to this very important chemical reaction. Following an introduction, the book goes on …

All marine organisms have been proven to be a veritable cornucopia of unusual steroid
metabolites, but some believe that marine sponges may provide the most diverse and …

This review describes the isolation from marine organisms of all secosteroids reported in the
literature from 1972 to 2004. Secosteroids are highly oxidized metabolites with bond …

Sterols of marine organisms have been found to be comprised of most complex mixtures.
Over 200 new monohydroxysterols have so far been identified from marine sources, and …

OsO4 catalyzes the oxidative cyclization of the 1, 5-dienes geranyl acetate (1) and neryl
acetate (2) to the cis-2, 5-bis (hydroxymethyl) tetrahydrofurans 3 and 4 respectively, in the …

A 10-step gram-scale synthesis of 9, 11-secosteroid pinnisterol E from the inexpensive
ergosterol is reported. This synthesis features a series of highly selective redox …

A synthetic approach to recently reported and structurally unique 11 (9→ 7) abeo-steroids
pleurocin A/matsutakone (1) and pleurocin B (2) was developed by reconsidering the …

A comprehensive review on the chemistry of Spongia sp. is here presented, together with
the biological activity of the isolated compounds. The compounds are grouped in …

The marine sponges (Porifera) are a unique group of sedentary organisms from which
several novel natural products are reported, many of which have useful biological activities …
