摘要：

The steric demand of an oxygen atom is less than that of a CH2 group in the kinetic resolution of chiral dienophiles with the enantiomerically pure dienes 1 and ent‐1 (R = OCH3). This realization led to the first differentiation between enantiotopic double bonds in a Diels–Alder reaction for the spirolactone 2 and spiroether 3. (Figure Presented.)
