An easily attainable bifunctional monosulfonamide derivative of DACH was an effective catalyst for Michael addition-hemiacetalization reactions, providing products with ees exceeding 99% under optimized conditions. High enantioselectivities were achieved with just 0.2% mol catalyst loading. The sulfonamide outperformed analogous thiourea and squaramide-based organocatalysts.
