  Abstract:  First coherent examples of stereocontrolled ring closure in 1-aza-3,7-dioxabicyclo[3.3.0]octane series were found to originate in the anomeric effects of the aminalic part of this heterobicyclic saturated system; experimental data were in agreement with the theoretical calculation; the roll of the bulky substituents is also pointed out.
