The first total synthesis of (±)-1-desoxyhypnophilin

The paper describes the first total synthesis of (±)-1-desoxyhypnophilin, a linear triquinane from the East African mushroom Lentinus crinitus which displays promising antimicrobial activity. A key feature is the use of a ring closing metathesis reaction with a tertiary allylic alcohol, in conjunction with a PCC induced oxidative rearrangement, to construct a cyclopentenone.
