## Abstract Conjugate addition of ethyl acetoacetate to 2,2′‐sulfonylbis(1,3‐diarylprop‐2‐en‐1‐ones) afforded a diastereom‐eric mixture (in a ratio of ∼65:35) of 4‐acetyl‐2,6‐diaroyl‐3,5‐diaryl‐4‐ethoxycarbonylthiane‐1,1‐dioxides differing in configuration at C‐4. The stereochemistry of the diaster
