我们已经证明了级联反应和一锅反应，它们构成了反电子需求的杂Diels-Alder反应和氧化芳构化，以提供取代的喹啉来生成芳香醛二胺和烯丙基硅烷。级联过程包括自动串联催化；Tf2NH激活这些机械上不同的反应。我们发现，从苯胺、醛和烯丙基硅烷开始的多组分工艺也是可行的。(C)2007爱思唯尔有限公司。保留所有权利。
We have demonstrated cascade and one-pot reactions, which constitute inverse electron demand hetero-Diels-Alder reaction and oxidative aromatization, to provide substituted quinolines to form aryl aldimines and allylsilanes. The cascade process involves an auto-tandem catalysis; Tf2NH activates these mechanistically distinct reactions. We have found that a multicomponent process starting from aniline, aldehyde, and allylsilane is also available. (c) 2007 Elsevier Ltd. All rights reserved.
