the synthesis of novel 6,7-dihydrodibenzo[b,j][1,7]phenanthrolinederivatives is described. In this two-step procedure, aldol addition and reductive cyclization methods are effectively utilized for the construction of C–C and C–N bonds. This highly efficient process proceeds under mild conditions, tolerates different functional groups, and provides various substituted 6,7-dihydrodibenzo[b,j][1,7]phenanthroline
