## Abstract A type of __C~2~__‐symmetrical bisprolinamide has been developed for the asymmetric aldol reaction between acetone and α‐keto esters, which furnishes the chiral tertiary alcohols in high yields (up to 99 %) with high enantioselectivities (up to 94 % __ee__). Aliphatic, heteroaromatic an

## Abstract Asymmetric [4 + 2] cycloaddition of β,γ‐unsaturated α‐keto esters (I) and (IV) with oxazolones (II) proceeds with excellent diastereoselectivity and high enantioselectivity (up to 97% e.e.) in the presence of a quinidine‐derived bifunctional organocatalyst (NQD).
