| Abstract: | A Lewis-acid-catalysed tandem Meinwald rearrangement/[3+2]-cycloaddition of epoxides with donor-acceptor cyclopropanes to synthesize varieties of cis-2,5-aryl-benzyl-substituted tetrahydrofurans is described. An enantioselective version of the same transformation was achieved using an InCl3-PyBOX catalyst system. A Lewis-acid-catalysed tandem Meinwald rearrangement/[3+2]-cycloaddition of epoxides with donor-acceptor cyclopropanes to synthesize varieties of cis-2,5-aryl-benzyl-substituted tetrahydrofurans is described. An enantioselective version of the same transformation is also presented using various BOX ligands. |
