The aldol reaction of a -branched aliphatic aldehydes 7 as different aldol donors with isatins 5 using catalyst 1a also gave the corresponding aldol products 8 in excellent enantioselectivities (up to 94% ee), showing that catalyst 1 was applicable for asymmetric aldol reactions of cycloalkanones, hydroxyacetones, and a -branched aliphatic aldehydes as AD and aromatic aldehydes, isatins as AA.
