Synthesis and mass spectral data of four potential biomarkers related to the C19 tricyclanes found in Australian oils and puget sound sediments

The synthesis of four potential biomarkers, 13α-, 13β-, 14α- and 14β-ethyl-8β(H)-podocarpane is reported. GC-MS comparison with an Australian oil C19 tricyclane and the mass spectra of two Puget Sound C19-terpanes evidenced non-identity of the synthetic compounds with the natural products; thus, proposed structures should be revised.
Total Synthesis of the Labdane Diterpenes Galanal A and B from Geraniol

The first total synthesis of galanal A and B has been achieved from naturally occurring geraniol. Key steps in this synthesis are the use of a Lewis acid assisted chiral Br?nsted acid (chiral LBA) mediated cationic polyene cyclization and a titanocene-mediated radical cyclization for the asymmetric assembly of the "AB" ring and the construction of the all-carbon quaternary center at the junction of the "BC" ring, respectively.
