Herein, we report a mechanisticinvestigation of an enantioselective tandem Mukaiyama aldol reaction, consisting of a carbon–carbon bond-forming reaction and a silylation protection step in which the enantioselectivity results exclusively from the silylation step. The reaction is carried out in the presence of a Lewis base paired with a chiral quarternary ammonium salt. Mechanistic studies indicate that
