Synthesis and cytotoxic activity of pyranocoumarins of the seselin and xanthyletin series

The synthesis of known (3-6) and new (7-10 and 14-22) coumarins in the seselin and xanthyletin series is described. The cytotoxic activity of compounds 3-22 was carried out in vitro on L-1210 cells. The most active compounds were 9, 16, 18, and 20 in the seselin series and 10, 17, and 19 in the xanthyletin series. Structure-activity relationships are discussed.
