Serendipitous synthesis of diaxial 2,4-diphenyl-3,7-dioxabicyclo[3.3.0]octane

Reduction of cis-3,4-dibenzoyltetrahydrofuran with BMS, very surprisingly yields diaxial 2,4-diphenyl-3,7-dioxabicyclo[3.3.0]octane in a reaction that contrasts sharply with processes involving equilibrating benzylic carbocations which yield the diequator

Synthesis and N.m.r. Spectra of 2,6- and 2,4-Diaryl-3,7-dioxabicyclooctanes

A series of isomeric 2,6- and 2,4-diaryl-3,7-dioxabicyclooctanes have been prepared via the corresponding threo, and erythro-dioxo-diesters.Comparison of their 1H and 13C n.m.r. spectra reveals small differences in chemical shifts and coupling constants which could be diagnostic in assigning structures to such compounds.The structure of 4-hydroxysesamin has been confirmed by direct correlation with sesamin.
