Abstract
A new, simple method for the synthesis of N-(trifluoroacetyl)-protected sulfilimines from sulfides by a transition-metal-free, one-pot protocol is presented. The salient features of this process include the use of low-cost 1,3-dibromo-5,5-dimethylhydantoin, mild reaction conditions, and a broad substrate scope. The safety and robustness of the method has also been demonstrated by operations on a kilogram scale. In addition, a chiral resolution of a corresponding sulfoximine was achieved on a large scale.

- 18 Calorimetric measurements revealed that THF solutions of DBDMH have a limited stability at 20 °C and should therefore be handled at 2–8 °C. Solutions of DBDMH in, for example, 1,4-dioxane are more robust and can be used as an alternative without a detrimental effect on quality or yield.
- 19 General Experimental Procedure for the Formation of N-(Trifluoroacetyl)-Protected Sulfilimines on a Laboratory Scale In an inert gas atmosphere, a mixture of the sulfide (34.7 mmol) and trifluoroacetamide (5.89 g, 52.1 mmol) in THF (20 mL) was added under ice cooling within 45 min to a suspension of NaH (60% in mineral oil; 1.25 g, 31.3 mmol) in THF (25 mL). Then, a freshly prepared solution of 1,3-dibromo-5,5-dimethylhydantoin (14.9 g, 52.1 mmol) in THF (37 mL) was added within 60 min at 20 °C. The mixture was stirred for 3 h; the reaction was quenched with 10% aq citric acid solution (35 mL), and toluene (70 mL) was added. The organic layer was washed with 25% aq sodium sulfite solution (35 mL) and water (3 × 40 mL). The solvent was removed by distillation, and the residue was purified by silica gel chromatography (EtOAc–n-heptane = 1:1).
