    • 3 is shifted toward the C=O⋯Yb dimer less than in 5b. Despite the consequent lower efficiency, the LIS effect experienced by the ethyl methyl signal is larger in 5a than in 5b, because in the diastereoisomer syn the C= O is closer to the Et group than in the diastereoisomer anti (the computed average distances between the carbonyl oxygen atom and the ethyl methyl hydrogens are 3.65 Å in 5a and 5.52 A in 5b).
