The HF/3-21G-optimized geometry of 2,3-dioxabicyclooct-5-ene (1) shows that its olefinic hydrogens are bent in the syn direction (with respect to the dioxy bridge) by 2.1 deg, thus giving rise to anti pyramidalization of the doubly-bonded carbon at

Introduction of a methoxycarbonyl group on the plane nonsymmetric double bond of 2,3-dioxa and 2,3-oxaza bicyclo[2.2.2]oct-5-enes brought about a clear-cut increase in syn selectivity of their reactions with 1,3-dipoles.
