Methoxy‐indolo[2,1‐a]isoquinolines 8a‐f and their dihydroderivatives 7a‐f were synthesized by Bischler‐Napieralski reaction of the (bromomethoxyphenyl)‐[2‐(methoxyphenyl)‐ethyl]acetamides 4a‐f, reduction, subsequent cyclization and dehydrogenation. They were tested for cytostatic activity in vitro using P388 D1, leukemia and MDA MB 231 mammary tumor cells. The trimethoxy‐5,6‐dihydroindoloisoquinoline
