The squaramide catalyzed enantioselective Michaeladdition of rhodanines to 2‐arylidene‐N‐tosylbenzofuran‐3(2H)‐imines has been established, which enables the formation of benzofurans bearing both rhodanine and sulfur‐containingtetrasubstitutedstereocenter structural motif in good to high yields with good to excellent enantio‐ and diastereoselectivities.
