    • In their studies of intramolecular N-H insertion reactions of α-diazo esters, McKervey and co-workers reported that dirhodium(II) tetrakis[(S)-mandelate]-catalyzed the N-H insertion of methyl 6-benzyloxycarbonylamino-2-diazohexanoate competed with C-H insertion and alkene formation, where the C-H insertion product cyclopentane with the cis stereochemistry of the substituents was produced in up to 28% ee: C.
