indolizino[3,2-c]quinolines, via the oxidativePictet–Spenglercyclization strategy. The condensation of several 2-methylpyridines with 2-bromo-2′-nitroacetophenone allowed for the rapid assembly of indolizines with a 2-nitrophenyl group at the C2 position. The subsequent reduction of the nitro group under mild conditions followed by oxidativePictet–Spenglercyclization with various aryl aldehydes in the
