ResumoThe transition state during the highly enantioselective abstraction (see picture) of the pro-S atom of N-Boc-pyrrolidine 1 by the alkyllithium reagent iPrLi/(−)-sparteine was investigated using ab initio molecular orbital calculations. The stability of the transition states was found to be controlled by steric parameters.
