Copycat: A highly enantioselective biomimetic aldol reaction of malonicacid half thioesters with a variety of aldehydes affords optically active β‐hydroxy thioesters by employing the cinchona‐derived sulfonamide organocatalyst 1. The synthetic utility of this protocol was demonstrated by performing formal syntheses of the antidepressants (R)‐fluoxetine, (R)‐tomoxetine, (−)‐paroxetine, and (R)‐duloxetine
