Substituted furo[2,3b]furans, furo[2,3b]furan-2-ols and furo[2,3b]furan-2-ones were synthesized in a stereoselective manner. The key steps were the reactions of α-lithio-nitriles and dilithio-carboxylates with mono-substituted oxiranes.

The synthesis of a key intermediate, 1,2,3,4,4a,5,6,7,8,8aβ-perhydro-4α-isopropyldimethylsilyloxy-4aα-isopropyldimethylsilyloxy-methyl-1α,2α-dimethyl-5-methylene-naphthalene-1β-carbaldehyde 31 , in the total synthesis of insect antifeedant clerodanes is described. The stereochemistry of this intermediate is proven by an X-ray analysis of one of its precursors e.g. 10α-acetoxy-7β-(1,3-dioxolan-2-yl)-3,3aβ,4,5,6,6aβ,7,8,9,10-octahydro-7α,8α-dimethyl-1H-naphtho[1,8aα-c] furan 25 .

Abstract New reagents for the stereoselective synthesis of 2-substituted perhydrofuro[2,3b]furanas are described. Ia the successful approach towards the latter compounds, the key steps were the addition of a aonolithio-2α-methoxy-3β-[(phenylsulfonyl)-methyilperhydrofuran to an aldehyde and a dilithio-2α-methoxy-3β-[(pheaylsulfonyl)-methyl]perhydrofuran to a carboxy1 derivative, respectively. The structures and conformations of the 2-tert-butylmtyl- and Z-isopropylper-hydrofuro [2,3b]furans were ...
