Cyclopropane derivatives chiroptical properties

Herrmann A, Ruettimann M, Thilgen C, Diederich F (1995) Multiple cyclopropanations of C70. Synthesis and characterization of bis-, tris-, and tetrakis-adducts and chiroptical properties of bis-adducts with chiral addends, including a recommendation for the configurational description of fullerene derivatives with a chiral addition pattern.

The present chapter is largely restricted to cyclopropane derivatives as data on other compounds with a three-membered ring are lacking in the literature. Generally, chiroptical properties intrinsic to the cyclopropane system as well as substituent effects of the cyclopropyl group on chiroptical properties of other types of molecules or chromophores, respectively, will be dealt with.
