摘要：

The plane-nonsymmetrical diene spiro(bicyclo[2.2.1]heptane-2,1'-[2,4]cyclopentadiene) (2) was synthesized, and the pi-facial stereoselectivity of its Diels-Alder cycloadditions with three cyclic dienophiles was examined. Adduct ratios were very similar, and the selectivity is surmised to be mainly the result of steric interactions at the transition state.
