Drimane-type sesquiterpenoids from fungi

Chinese Journal of Natural Medicines, 2022
Sesquiterpenoids are comprised of three C5 units and derived from farnesyl diphosphate. In these C15 family of terpenoids, drimane-type sesquiterpenoids are unique as their chemical structure of decahydronaphthalene along with the methyl group decorations resemble the A/B rings of labdane derived diterpenoids and the eastern part of many meroterpenoids.

Synthesis of Drimanes from (+)-Larixol

Synthesis, 2000
The selective transformation of the side chain of larixol 1 to a functionalized one-carbon moiety leads to 6,8-diacetoxydrimenal 13, which was converted to the drimanes (-)-albrassitriol (2), (-)-drimenol (3), (-)-uvidin C (4) and (-)-epi-albrassitriol (5).

Synthesis of biologically active drimanes from (−)-sclareol

Tetrahedron Letters, 1994
Abstract The enantiospecific synthesis of drimenyl acetate (8), a key intermediate in the synthesis of biologically active drimanes, and albicanyl acetate (14), potent fish antifeedant, from sclareol (1), are described. Also a short and efficient synthesis of polygodial (22), from albicanyl acetate (14), is shown.

Antibacterial Drimane Sesquiterpenes from Aspergillus ustus

Journal of Natural Products, 2020
Bioactivity-guided isolation of Aspergillus ustus led to the discovery of five new drimane sesquiterpenes, named ustusal A, ustusolate F and G, and ustusoic acid A and B, 1-5 respectively. Structural elucidation of these fungal terpenes relied on 1D and 2D NMR techniques, high-resolution mass spectrometry, and chiroptical properties.
