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

Dimeric [Ca(OCtBu,) ,] is synthesized from 2a and HOCIBU, by analogy to Equation (c); colorless crystals, moderately soluble in n-pentane. readily soluble in toluene and diethyl ether. Warming under high vacuum (185'Ci mbar) gives a moderate yield of trimeric [Ca(OCHtBu,),] as a colorless sublimate
