The Rh2(OAc)4-catalysed C-H insertion in chiral ester diazoanilides was investigated and was found to yield 4-substituted 2-pyrrolidinones with moderate to high e.e. (37-98%) after decarbalkoxylation. Electronic effects were found to oppose steric effects in influencing the enantioselectivity of the reaction in N-arylethyl diazoanilides.
