Abstract

Abstract e, e, e-Trisadducts 13 and 15 have been prepared by a highly regioselective threefold cyclopropanation of tripodal malonates 10 and 12 with C 60. The yield and regioselectivity depend on the length and structure of the tethers that connect the malonate units to the focal benzene core of 13–15. As a consequence of the template-directed synthesis, all e, e, e-trisadducts were formed as in/out isomers exclusively and contain two ...
