hill: The products from the hetero‐Diels–Alder reaction of acrolein with methyl vinyl ketone arise from a single transition state (see scheme) and trajectory studies accurately predict the selectivity. In an extension of the dynamic matching idea of Carpenter, the product formed is determined by the direction of motion passing through the transition state. Recrossing occurs extensively and decreases
上下山:丙烯醛与甲基乙烯基酮的异狄尔斯-阿尔德反应的产物来自单一过渡态(见方案),轨迹研究准确预测了选择性。在 Carpenter 的动态匹配思想的扩展中,形成的乘积是由运动方向通过过渡态决定的。重交广泛发生并减少次要产物的形成。
