Lewis acid catalyzed alteration of annulation pattern allowed formation of arylquinolines via C–H functionalization of nitrosoarenes and C–C cleavage of (epoxy)styrene.
The carbonylativeringexpansion reaction of 3,6-dihydro-2H-1,2-oxazines proceeded in the presence of Co2(CO)8 to give 4,7-dihydro-1,3-oxazepin-2(3H)-ones in up to 53 % yield.
