Abstract

R ti I cerium reagent t THF,-78%. 30min cyclopentanone derivative rac-1 (entries 9, 11, 13 and 15) proceeds with good to very good diastereoselectivities (87-94% de), which are among the best reported for the addition of organometallic reagents to simple cycIopentanones.['O," 1 In order to establish the width of application of the new cerium derivatives in carbonyl addition reactions, the addition of organocerium reagents derived ...
