Synthesis and Structural Characterization of a New Class of Strong Chiral Brønsted Acids: 1,1′‐Binaphthyl‐2,2′‐bis(sulfuryl)imides (JINGLEs)

Abstract

Abstract We herein present the first synthesis of 1,1′‐binaphthyl‐2,2′‐bis(sulfuryl)imides (JINGLEs). This new class of chiral Brønsted acids was synthesized in one step from the corresponding BINOLs and imidobis(sulfuryl chloride). A total of six enantiopure 1,1′‐binaphthyl‐2,2′‐bis(sulfuryl)imides, carrying different 3,3′‐substituents, were synthesized and characterized, inter alia, by X‐ray crystallography.
