A novel [4+1] spiroannulation of o‐ & p‐bromophenols with α,β‐unsaturated imines has been developed for the direct synthesis of a new family of azaspirocyclic molecules. Notably, several other halophenols (X=Cl, I) were also applicable for this transformation. Moreover, a catalytic asymmetric version of the reaction was realized with 1‐bromo‐2‐naphthols by using a chiral ScIII/Py‐Box catalyst. Mechanistic
已经开发了一种新颖的[4 + 1]邻和对溴苯酚与α,β-不饱和亚胺螺环合成的方法,用于直接合成新的氮杂螺环分子家族。值得注意的是,其他几种卤代酚(X = Cl,I)也适用于该转化。此外,通过使用手性Sc III / Py-Box催化剂,使用1-溴-2-萘酚实现了反应的催化不对称形式。机理研究表明,该多米诺反应是通过苯酚衍生物在其卤代位置的亲电触发的脱芳香化作用进行的,然后通过基于自由基的S RN 1机理用N-亲核试剂进行卤素置换。

A transition‐metal‐free Claisen rearrangement/cyclization reaction was developed for the synthesis of naphthofuran derivatives from bromonaphthyl 3‐phenylallyl ethers. The nature of the base employed in this reaction plays an important role in determining the ratio for the formation of naphthofuran and naphthol products. By using K2CO3 as base and DMF as solvent, we have synthesized a variety of functionalized
开发了无过渡金属的克莱森重排/环化反应,用于从溴萘基3-苯基烯丙基醚合成萘呋喃衍生物。该反应中使用的碱的性质在确定萘呋喃和萘酚产物的形成比例中起重要作用。通过使用K 2 CO 3作为碱和DMF作为溶剂,我们合成了各种官能化的萘呋喃,其产率高至高(49-92%),并且具有令人满意的选择性。
