Diastereoselectivities up to 98% de have been reached in kinetic resolutions of the racemic acrolein dimer 1 by reaction with the chiral phosphonates 2 . Depending on the choice of substituents on the phosphoryl group (R CF 3 CH 2 , C 2 H 5 ), either ( E )‐ 3 or ( Z )‐ 3 , both of which are versatile synthetic building blocks, can be obtained as the major product. The dominant isomer for ( Z )‐ 3 is the ( S ) isomer and for ( E )‐ 3 the ( R ) isomer.
