Chemoselective oxa-Diels–Alder reactionsbetween electrically neutral 1,3-dienes and various aldehydes were achieved using the commercially available silver tetrafluoroborate (AgBF4) as catalyst. This catalytic process has high functional group tolerance. Heteroatoms at the β-position of the aryl aldehydes can greatly promote the reactivity of the substrates even with heterocyclic aldehydes that were

We have developed a new base-promoted intermolecular cascade cyclization reaction of substituted 3-aryl(heteroaryl)-3-chloroacrylaldehydes and tetrahydroisoquinolines in one pot. The reaction provides a facile and practical synthesis of pyrrolo[2,1-a]isoquinolines. A number of pyrrolo[2,1-a]isoquinolines were synthesized in moderate to high yields (up to 97%).
我们已经开发了一种新的碱促进的在一锅中取代的3-芳基(杂芳基)-3-氯丙烯醛和四氢异喹啉的分子间级联环化反应。该反应提供了吡咯并[2,1- a ]异喹啉的简便实用的合成方法。合成了许多吡咯并[2,1- a ]异喹啉,中度至高产率(高达97%)。
Synthesis of Substituted Azulenes via Pt(II)-Catalyzed Ring-Expanding Cycloisomerization
Substituted azulenes, valuable structures for electronic devices and pharmaceuticals, have been synthesized by the platinum(II)-catalyzed intramolecular ring-expanding cycloisomerization of 1-en-3-yne with ortho-disubstituted benzene. This novel method provides an alternative route for the efficient synthesis of substituted azulenes. The reaction mechanism of selected catalytic transformations was

A one-pot procedure involving a four-component Ugireaction followed by an intramolecular Diels–Alder reaction/HCl elimination cascade has been developed to provide rapid access to the isoindolinone framework in a diversity-oriented fashion. The scope of the process has been investigated with respect to all fourcomponents, and a comparison between the one-pot and sequential approaches is given. The
已经开发了一种涉及四组分 Ugi 反应,然后是分子内 Diels-Alder 反应/HCl 消除级联反应的一锅法,以提供以多样性为导向的异吲哚酮框架的快速访问。已经针对所有四个组件研究了该过程的范围,并给出了一锅法和顺序方法之间的比较。已经探索了通过 Suzuki 耦合进行后期一锅功能化的可能性。
