The first Rh-catalyzed C–H amidation of pyridines is reported. The incorporation of a substituent at the C2 position both is crucial to the success of this transformation and provides considerable scope for further elaboration of the resulting products. Among these compounds, 2-chloropyridines allow access to a selection of intermediates including a versatile azaquinazoline scaffold.
据报道,吡啶第一次被Rh催化的C–H酰胺化反应。在C 2位上引入取代基不仅对这种转化的成功至关重要,而且为进一步精制所得产物提供了相当大的范围。在这些化合物中,2-氯吡啶允许使用各种中间体,包括通用的氮杂喹唑啉骨架。
