Here we report a novel Rh-catalyzed C−H/C−H alkenylation of N-arylmethanimines with vinylene carbonate acting as a vinylene unit. Forty examples of C3,C4-nonsubstituted quinolines were achieved from commercially available starting materials. This identified process features an exceedingly simple system, a lower loading of catalyst, and the capacity for postfunctionalization with bioactive molecules
在这里,我们报告了一种新的 Rh 催化的N-芳基甲亚胺的 C-H/C-H 烯基化,其中碳酸亚乙烯酯作为亚乙烯基单元。C3,C4-非取代喹啉的 40 个例子是从可商购的起始材料中获得的。这一确定的工艺具有极其简单的系统、较低的催化剂负载量以及生物活性分子后功能化的能力。
