The configuration of the alkylation products (e.g., 6 and 7) are fully in accord with this analysis. In summary, chiral auxiliary compounds (3) of a new shape have been described, and their action can be related to the stereoelectronics of enolate alkylations. The asymmetric environment of the auxi
