A new method to regulate the diastereoselectivity of reactions of donor-acceptor cyclopropanes by ligand control has been found. The method has been demonstrated for [4+2]-cyclodimerization of 2-(1-naphthyl)cyclopropanedicarboxylate to give polysubstituted tetrahydrophenanthrenes in the presence of GaCl3 as an example. If tetrahydrofuran is used as the ligand, the trans,trans-isomer is formed exclusively, whereas if 1-formylpyrene is used, diastereoselectivity changes almost completely and the trans,cis-isomer is formed. A possible mechanism of diastereoselectivity change has been suggested and studied.
