Diastereoselective Protonation of Chiral Enolate with Chiral Imides. -Protonation of the lithium enolate (I) of (-)-menthone by chiral imides such as the (R)-imide of conditions (A) generates mainly the cis ketone (III). The selectivity of this process can be completely reversed by using the corres
