[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).

The dirhodium tetracarboxylate, Rh(2)(S-TCPTAD)(4), derived from adamantylglycine, is an effective chiral catalyst for both inter- and intramolecular C-H aminations. [reaction: see text]
