Abstract

The structure of the title compound, C₂₆H₃₁NO₃, was determined by X-ray crystallography. It was found to be a unique bridged tricyclic nitroso acetal. Notable features include a chair conformation of the tetrahydro-1,2-oxazine ring and a highly pyramidalized N atom [Σ_angles = 314.2(6)°]. The configurations of the five contiguous stereogenic centers in the nitroso acetal establish that the tandem cycloaddition sequence proceeded via an exo-[4+2]/endo-[3+2] pathway.
