A total synthesis of the bis-deoxylophotoxin 25a, the probable biological precursor to the neurotoxin lophotoxin 1 is described. The synthesis uses a strategy based on sequential carbanion alkylation and Stille coupling between the chiral building blocks 5 and 6, leading to the furanocembranolide 23, following by functional group manipulation.

products, e.g. lophotoxins, pukalides, bipinnatins, based on: i) an intramolecular cyclisation of an alpha,beta-unsaturated acyl radical intermediate into a conjugated enone, and ii) an intramolecular Stille coupling reaction involving a 2-stannylfuran and a vinyl iodide, are described. A total synthesis of bis-deoxylophotoxin , the probable biological precursor to the neurotoxin lophotoxin, isolated from
