• Understanding reactivity and regioselectivity in Diels–Alder reactions of a sugar-derived dienophile bearing two competing EWGs. An experimental and computational study

  The effect of an extra EWG in the reactivity and regioselectivity in Diels-Alder reactions of beta-cyanolevoglucosenone and 4 different dienes was studied by a joint computational and experimental study. Conceptual DFT analysis successfully predicted an important enhancement in the reactivity, and correctly anticipated the regioselectivity in the reactions with isoprene. However, this static treatment

  通过联合计算和实验研究，研究了额外的EWG对β-氰基烯丙基葡糖醛酮和4种不同二烯的Diels-Alder反应的反应性和区域选择性的影响。DFT概念分析成功地预测了反应性的重要提高，并正确预测了与异戊二烯反应的区域选择性。然而，当处理涉及取代的蒽作为二烯的反应的区域化学偏好时，该静态处理失败。MPW1K / 6-31G *计算正确地再现了实验观察结果。基于收集的数据，我们发现，当处理没有清晰电子激活位置的二烯和亲二烯体时，相互作用原子的锥体化程度决定了DA反应的区域选择性。

  experimental and computational study was conducted to assess the effect of chlorine and bromine substitution in Diels–Alder reactions involving chiral α-halo enones as dienophiles. An important rate enhancement was observed in the case of acyclic dienes, while the use of cyclic dienes resulted in prolonged reaction times and lower yields. DFT calculations suggest that these reactions are governed by finely

  An appealing inversion in the regiochemical outcome of Diels–Alder reactions between levoglucosenone (1) and its α-bromo derivative (5) with isoprene (2) was studied computationally. Based on different DFT calculations we concluded that both reactions should display the same regioselectivity. This result was further validated experimentally.
