Yield	Reaction Conditions	Operation in experiment
98%	With sodium carbonate In 1,4-dioxane; water at 10 - 20℃; for 2.00 h;	Sodium carbonate (4.6 g, 43.6 mmol) and L-cystine (5.0 g, 20.8 mmol) were dissolved in water (200 mL). The resulting solution was cooled to 10° C. FmocCl (11.85 g, 45.8 mmol) was dissolved in dioxane (80 mL), and the resulting solution was added dropwise to the aqueous solution of L-cystine. The solution was stirred for 2 h at 10° C. and allowed to gradually warm to room temperature. A thick white precipitate was obtained that was filtered onto a sintered glass funnel. The product was triturated with diethyl ether (50 mL) and dried in vacuuo for 2 d. N,N'-Bis(Fmoc)-L-cystine (14.0 g, 98percent yield) was obtained as a white powder.

Yield	Reaction Conditions	Operation in experiment
94%	With sodium carbonate In water; acetone at 50℃;	General procedure: Procedure adapted from that of Agan et al[28]. 407 mg Na₂CO₃ (3.82 mmol) was dissolved in 30 mL distilled water with stirring. 35 mL acetone was then added followed by 1.91 mmol L-cystine or L-selenocystine. The temperature of the reaction was brought to 50 °C and 1.93g (5.73 mmol) Fmoc-OSu was added in portions over 5 minutes. Heating was removed and the reaction was allowed to progress overnight. At the end of this time, 40 mL 1 HCl was added followed by 50 mL EtOAc. Following vigorous shaking, the layers were separated, and the organic portionwas dried over MgSO₄ and concentrated in vacuo to afford the crude bis N-Fmoc dichalcogenide which was purified by recrystallization from CHCl₃.
