摘要
Herein, we report a urea derived directing group for mild and highly selective oxidative C-H bond olefination. Subsequent intramolecular Michael addition affords dihydroquinazolinones in good yields. The N-O bond of the urea substrate exhibits superior oxidative behaviour compared to a variety of other external oxidants.
