[reaction: see text] The dirhodium tetracarboxylate, Rh2(S-PTAD)4, derived from adamantylglycine, is a very effective chiral catalyst for carbenoid reactions. High asymmetric induction was obtained in Rh2(S-PTAD)4-catalyzed intramolecular C-H insertion (94% ee), intermolecular cyclopropanation (99% ee), and intermolecular C-H insertion (92% ee).

Disclosed are compounds having the following formula:
in which Z11 is selected from a substituted or unsubstituted saturated adamantyl or other polycyclic group and a substituted or unsubstituted branched acyclic group containing at least 5 carbon atoms at least one of which is a tertiary carbon; and in which Z12 is a cyclic imide. Methods of using these compounds as chiral catalysts for carbenoid reactions and for enantioselective C—H aminations are also described.
