摘要：

: The room temperature, endo-selective LUMOdiene-controlled Diels-Alder reactions of N-(phenylsulfonyl)-and N-(methylsulfonyl)-4-(ethoxy-carbonyl)-l-aza-l,3-butadiene (3–4) are described, and the results represent a demonstration of the [4 + 2] cyclo-addition rate acceleration achievable through noncom-plementary azadiene substitution. © 1990, American Chemical Society.
