  On the origin of changes in topicity observed in Diels–Alder reactions catalyzed by Ti–TADDOLates

  摘要：

  New C-2 symmetric TADDOLs containing different groups at the 2-position of the dioxolane ring have been prepared. The Ti catalysts derived from these have been studied in the Diels-Alder reaction of cyclopentadiene and (E)-2-butenoyl-1,3-oxazolidin-2-one. Substituents at the C-2 position of the dioxolane ring can play an important role in determining the selectivity as well as the nature of the major isomer. This effect is more important for TADDOLs containing bulky aromatic groups such as 3,5-dimethylphenyl- or 1-naphthyl at the alpha -positions. Experimental evidence supports the hypothesis that pi-pi. interactions between aromatic groups at the C-2 and the ones at the a-positions are critical in this respect. (C) 2001 Elsevier Science Ltd.

  An acid-catalyzed Prins/semipinacol rearrangement cascade reaction of hydroxylated pinene derivatives that leads to tricyclic fenchone-type scaffolds in very high yields and diastereoselectivity has been developed. Quantum chemical analysis of the selectivity-determining step provides support for the existence of an extremely flat potential energy surface around the transition state structure. This

  已经开发出羟基化蒎烯衍生物的酸催化的 Prins/semipinacol 重排级联反应，该反应以非常高的产率和非对映选择性得到三环芘酮型支架。选择性决定步骤的量子化学分析为过渡态结构周围极其平坦的势能面的存在提供了支持。这种过渡态结构似乎是双峰的，即在通过过渡态分叉 (PTSB) 的动态控制下，fenchone 型三环支架优先于竞争性形成冰片（樟脑型）骨架。
