The [Rh2(OAc)4]-catalyzed addition of methyl diazoacetate to N-benzylideneaniline (1a) afforded the imine cis-2 in 35% yield. Under catalysis by chiral RhII catalysts, however, only racemic 1a was produced, and the yield was low. In the presence of dimethyl maleate, aziridine formation was suppressed, and an intermediate ylide 6 was trapped as cycloadduct 7. No aziridines were obtained, however, from
