Evolution of a Synthetic Strategy for Garsubellin A.
Garsubellin A is a thirty-carbon meroterpenoid capable of enhancing the enzyme choline acetyltransferase whose decreased level is associated with the symptoms of Alzheimer's disease. Due to the potentially useful biological activity along with the novel molecular architecture, this plant metabolite has remained a popular synthetic target. Herein we report a full account of our synthetic investigations that have led to the enantioselective total synthesis of garsubellin A, establishing its absolute stereostructure. The protecting group-free, twelve-step synthetic route has enabled the syntheses of the natural (-)-garsubellin A and its unnatural (+)-antipode.

Progress toward the Synthesis of garsubellin A and related phloroglucins: the direct diastereoselective synthesis of the bicyclo[3.3.1]nonane core.
[reaction: see text] A highly diastereoselective single-step cyclization reaction provides access to the bicyclo[3.3.1]nonane core of the polyprenylated phloroglucin natural product garsubellin A. Further elaboration to a more functionalized analogue involves a sequential Claisen rearrangement/Grubbs olefin cross-metathesis strategy. Additionally, this strategy was extended to the preparation of the bis-quaternary carbon array found at the bridgehead positions of the phloroglucin natural products.
