    • The obtained results in reaction of (5)-5 and (5)-3 suggest that reaction rates for enolization and nucleophilic addition processes must be similar.

    • A similar situation had been found in reactions of (5)-5 with aldimines (ref 9) but being the reagents with the same configuration at sulphur those conforming the matched pair.

    • note
    • These transition states would not be negligible for N-sulfinylaldimines and would explain the differences in their behaviour with respect to the N-sulfinylketimines.
