## Abstract We have achieved a 100 gram‐scale production of __anti__‐(2__S__,3__S__)‐β‐(__p__‐benzyloxy‐__m__‐chloro)phenyl‐__N__‐trifluoroacetyl‐L‐serine methyl ester (**1**) in high yield with high diastereo‐ and enantioselectivities based on a catalytic asymmetric Mukaiyama aldol reaction. The u
