Total Syntheses of Hirsutic Acid C and Complicatic Acid

The linearly fused tricyclopentanoids hirsutic acid C(1) and complicatic acid (2) were synthesized from the methanoindene 12 in a highly stereoselective manner.

Chemoenzymatic total syntheses of the linear triquinane-type natural products (+)-hirsutic acid and (-)-complicatic acid from toluene

Total syntheses of title natural products, 1 and 2, have been achieved using the cis-1,2-dihydrocatechol 7 as starting material. Compound 7 is readily obtained in large quantity and enantiomerically pure form through the whole-cell biotransformation of to

An Efficient, Enantioconvergent Total Synthesis of Natural Hirsutic Acid C

A stereocontrolled total synthesis of natural hirsutic acid C, a linearly fused triquinane from Stereum hirsutum, has been achieved through the use of an efficient asymmetric hydroboration and two highly selective three-carbon annelations.

Iterative Three-Carbon Annelation. A Stereoselective Total Synthesis of (+/-)-Hirsutic Acid C

Iterative olefin annelation has been used for the synthesis of hirsutic acid C, a linearly fused tricyclopentanoid fungal metabolite from Stereum hirsutum and Stereum complicatum.
