Abstract

A general approach to the synthesis of optically pure 3,3′‐diaryl chiral sulfonimides (CSIs) from racemic BINOL has been developed. ortho‐Lithiation is directed by the sulfonyl groups, and the resulting dihalides serve as the common precursors for the aryl‐substituted CSIs.

The enantioselective catalysis of organic reactions that involve small organic molecules, known as organocatalysis, has become a rapidly growing area of research, as it offers operational simplicity together with mild reaction conditions and is environmentally benign. [1] Although organocatalysis ha
