Abstract
Summary of main observation and conclusionDirecting strategy has been extensively exploited to maintain activity and selectivity for the rapid access to functionalized molecules and pharmaceutical targets. However, ‘one‐to‐one’ activation model was usually achieved through traditional directing strategy. Herein, we achieved ‘one‐to‐two’ activation model by slight modification of simple and practical ketoxime and amide functionality. With judicious choice of directing groups, Csp3—H and Csp2—H bond alkynylation reaction, and more significantly, dehydrogenative Csp3—H alkynylation, were realized, enabling the regio‐divergent late‐stage modifications of pharmaceuticals.
