Ru(II)-catalyzed oxidative (4+3) C–H/C–H annulation of 2-aryl-4H-pyrido[1,2-a]pyrimidin-4-ones with allyl alcohol

A ruthenium(II)-catalyzed direct oxidative (4+3) C–H/C–H annulation of 2-aryl-4H-pyrido[1,2-a]pyrimidin-4-ones with allyl alcohol has been described. The developed method yielded corresponding annulated products in moderate to good yields. In addition, based...
