In situ reduction of hydrido-tris-(3,5-dimethylpyrazolyl)borato(trioxo)
rhenium(V) with triphenylphosphine or triethylphosphite leads to a reactive
rhenium(V) species that catalytically deoxygenates epoxides at 75-105° ...
Two approaches to the tricyclic core of the furanoeremophilane
sesquiterpenoids are described. The first approach entails a projected Diels-Alder/retro Diels-Alder reaction of an acetylenic oxazole 64. Construction of
