• Efficient acetalisation of aldehydes catalyzed by titanium tetrachloride in a basic medium
  作者：Angelo Clerici、Nadia Pastori、Ombretta Porta

  DOI：10.1016/s0040-4020(98)00982-x

  日期：1998.12

  The acetalisation of aliphatic and aromatic aldehydes is achieved in a basic medium by using catalytic amount of Ti(IV) chloride in MeOH in the presence of NH3 or Et3N. The present protocol shows many advantages over the well known base or acid catalysis: in fact, in contrast to base-promoted acetalisation, aldehydes with electron-rich carbonyl groups react easily, enolizable aldehydes do not undergo

  在碱性介质中，通过在NH 3或Et 3 N的存在下在甲醇中使用催化量的Ti（IV）氯化钛（IV），可以在碱性介质中实现脂肪醛和芳香醛的缩醛化。：实际上，与碱促进的缩醛化反应相反，带有富电子羰基的醛容易反应，可烯化的醛不会发生醛醇缩合，并且与酸催化相反，在制备苯丙酸酯时不会发生双键迁移α，β-不饱和缩醛。图选项
• Unusual Carbon−Carbon Bond Formations between Allylboronates and Acetals or Ketals Catalyzed by a Peculiar Indium(I) Lewis Acid
  作者：Uwe Schneider、Hai T. Dao、Shu̅ Kobayashi

  DOI：10.1021/ol100450s

  日期：2010.6.4

  mechanism is proposed in which a single InI center acts as a dual catalyst to activate both reagents sequentially. Contrary to the classic γ-selectivity of allylsilanes (Hosomi−Sakurai reaction), this InI-catalyzed borono variant displays distinct α-selectivity. Substrate scope and functional group tolerance proved to be excellent.

  在I OTf中，已发现它是有效的路易斯酸催化剂，用于用烯丙基硼酸酯对乙缩醛或缩酮进行前所未有的亲核取代。提出了一种超金属化S N 1机制，其中单个In I中心充当双重催化剂，以依次激活两种试剂。与烯丙基硅烷的经典γ选择性（Hosomi-Sakurai反应）相反，此In I催化的硼烷变体表现出独特的α选择性。底物范围和官能团耐受性被证明是极好的。

  phosphonyloxylation of 1,4-bis- (dibromomethyl)benzene with P(IV) acid methyl esters. The reaction of 4-(dibromomethyl)benzaldehyde with ortho esters in the presence of sulfuric acid gave the corresponding acetals, whereas in the presence of ZnCl2 terephthalaldehyde bis-acetals were formed. 4-(Dibromomethyl)benzaldehyde and its acetal were converted to methyl 4-(dibromomethyl)- and 4-(dimethoxymethyl)benzoates which

  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。
