supporting information; experimental part, p. 4736 - 4740 (2011/08/06)
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. The Royal Society of Chemistry 2011.
APPROACH TO THE 1-METHOXY-2-BENZIMIDAZOLINONES

With t-butyl hypochlorite the 1-methoxy-3-arylureas are easily converted into the unstable corresponding 1-chloro-1-methoxy-3-arylureas.Cyclization of the latter under basic conditions gives the 1-methoxy-2-benzimidazolinones.The two steps can be carried
