WebThe E / Z energy differences that are observed for aliphatic ketones indicate an possible alternative explanation for the source of stereochemistry in (Ipc)2BCl reductions. If one of the two Ipc groups is much more likely to transfer a hydrogen to the carbonyl group than the other, then the enantiomeric excess of the product will be directly related to the E / Z …
