2-Formyl Benzamides from an N-Phthalimidoyl Sulfoximine

Under mild conditions, an N-phthalimidoyl sulfoximine undergoes aminolysis to provide a wide range of 2-formyl benzamides in good to high yields. An unprecedented variant of McFadyen-Stevens reaction explains the product formation. The applicability of the products as building blocks for nitriles and alkynes has been demonstrated.
