Abstract In our search for potential anticancer agents, a series of 8-and 9-phenylamino-3, 4- tetrahydro-phenanthridine-1, 7, 10 (2H)-triones with substituent variations at 6-, 8-and 9- positions were prepared using a highly efficient sequence involving: a) solar photoacylation reactions of benzoquinone with arylaldehydes, b) one-pot procedure for the synthesis of 3, 4- dihydrophenanthridine-1, 7, 10 (2H)-trione intermediates from acylhydroquinones and c) ...
