A simple and efficient stereoselective synthesis of clonostachydiol was achieved using ethyl (R)-3-hydroxybutanoate 5 and methyl (R)-2-hydroxypropanoate 12 as readily available starting materials. The key steps involved in the synthesis were MacMillan α-hydroxylation, Horner-Wadsworth-Emmons (HWE) olefination, a Grignard reaction, and Hoveyda-Grubbs IInd generation catalyzed ring closing metathesis (RCM).

Using HPLC/microtiter-plate-based generation of activity profiles the extract of a marine alga-derived fungus, identified as Gliocladium sp., was shown to contain the known strongly cytotoxic metabolite 4-keto-clonostachydiol (1) and also clonostachydiol (2) as well as gliotide (3), a new cyclodepsipeptide containing several D-amino acids. The absolute configuration of 1 was elucidated by reduction to 2, and two further oxidized derivatives of clonostachydiol (5, 6) were prepared and evaluated for biological activity.
