Description
Summary:A visible-light-induced metal-free cascade cyclization of cyclic -sulfonyl ketimines with -arylglycines for the construction of -sulfonamide-fused imidazolidines was developed. The procedure employed 3 mol% of eosin Y as the photocatalyst at room temperature under visible light irradiation, providing various -sulfonamide-fused imidazolidines in good yields (32 examples, up to 86% yields).
