The structure of the title compound, C31H39NO7Si, was determined and found to be a fused tricyclic nitroso acetal. Remarkable features include a twist-boat conformation of the tetrahydro-1,2-oxazine ring and a highly pyramidalized N atom [Σ(angles) = 310.6(6)°]. Three of the contiguous stereocenters in the nitroso acetal are of the same correct relative and absolute configuration as is found in (+)-crotanecine.
