A facile, practical and environmentally attractive protocol for the direct diversification of N-heterocycles under ambient, metal- and base-free conditions was developed.
在常温、无金属和无碱条件下,开发了一种简便、实用且环境友好的直接多样化N-杂环的协议。
Copper-Catalyzed Cross-Dehydrogenative C–N Bond Formation of Azines with Azoles: Overcoming the Limitation of Oxidizing N–O Activation Strategy
Here, we report the copper-catalyzed C2 selective cross-dehydrogenative C-N bond formation of azines with azoles. This straightforward method enables us to address the key limitation of prior N-O activation strategy in C2 amination of azines. The wide substrate scope, high functional group tolerance, and ease of operation of the present method are expected to promote its potential application in synthetic chemistry.
