Separation of an extract of Streptomyces citreus CBS 109.60 by column
chromatography and preparative gas chromatography yielded the novel se
squiterpene alcohol 1, whose structure and relative conformation were
established by spectroscopic means. Comparison of the its spectral dat
a with compounds of known absolute configuration led to assignment of
the stereochemistry at C-4 and C-7. Thus, 1 was assigned as 4S, 7R-ger
macra-1 (1O)E, 5E-diene-11-ol.
