Regio/diastereo-controls of the Bingel-type biscyclopropanation of fullerene by using bismalonates with a Tröger base analogue-derived tether
Access this Article
Four kinds of bismalonates tethered with a Tröger base derivative were synthesized and used for the double Bingel reaction of fullerene. The regio/diastereoselectivities of the reaction were highly influenced by the structure of the Tröger base derivatives. Heteroaromatic analogues of the Tröger base were found to be applicable as the core of the tether.
