(Chemical Equation Presented) In one easy step, doubly activated cyclopropanes 1 can be transformed into furoquinoline derivatives 2 through a tandem ring-opening/recyclization reaction mediated by SnCl4·5 H2O. A variety of substrates 1 derived from cheap starting materials were converted into the corresponding furoquinolines in good to excellent yields with high chemo- and regioselectivity. R = H, Me, OMe, Cl, or aromatic group is naphthyl.

A variety of 7,8-dihydrobenzo(k)phenanthridines (4a-h) have been synthesized by the AlCl3-catalysed rearrangement of 4-phenyl-2,3-dihydrofuro(2,3-b)quinolines (1a-h).Treatment of 4 with POCl3 affords the corresponding 6-chloro-7,8-dihydrobenzo(k)phenanthr
