Ts. Kaufman, SYNTHESIS AND MASS-SPECTRAL DATA OF 4 POTENTIAL BIOMARKERS RELATED TOTHE C-19 TRICYCLANES FOUND IN AUSTRALIAN OILS AND PUGET-SOUND SEDIMENTS, Synthetic communications, 25(8), 1995, pp. 1205-1221
The synthesis of four potential biomarkers, 13 alpha-, 13 beta-, 14 al
pha- and 14 beta-ethyl-8 beta(H)-podocarpane is reported. GC-MS compar
ison with an Australian oil C-19 tricyclane and the mass spectra of tw
o Puget Sound C-19-terpanes evidenced non-identity of the synthetic co
mpounds with the natural products; thus, proposed structures should be
revised.
