is effective for the enantioselectiveacylation and kineticresolution of benzylic secondaryalcohols. The enantioselectiveacylation has now been extended to secondaryalcohols bearing electron-withdrawing groups such as halides and other heteroatoms. The level of selectivity is modest to good and is sufficient for determining configuration using the competing enantioselective conversion method. A

Bias voltage-dependent scanningtunnelingmicroscopy (STM) experiments revealed the diastereoselectivity of the bilayer with respect to both the intrinsic chirality of the building blocks and the supramolecular chirality of the self-assembled networks. Top and bottom layers within the same crystalline domain were composed of the same enantiomers but displayed opposite supramolecular chiralities.
