摘要

An NMR study of a 1: 1 mixture of a chiral lithium amide (4a) and n-BuLi shows that depending on the solvent employed (E_t2O or THF) a mixed aggregate can form in proportions that are directly related to the ees measured during the enantioselective alkylation of o-tolualdehyde by these same species.
