Abstract
N-H-Aziridines undergo efficient ring-opening reactions with aromatic and aliphatic thiols in liquid sulfur dioxide as reaction medium. Due to the Lewis acidic nature of SO2, these reactions do not require any other catalytic additives. The expected β-alkyl/arylthio-amines (β-amino thioethers) are obtained with excellent β-regioselectivity. The developed reaction conditions are compatible with chiral starting materials the enantiomeric purity of which is conserved in the corresponding products. This method is also useful for direct synthesis of carbohydrate–amino acid conjugates and 2-iminothiazolidine derivatives.

- 27 General Procedure for Aziridine Ring Opening at –10 °C (S)-Aziridine-2-carboxamide (1; 0.10 g, 1.17 mmol, 1 equiv) and 4-chlorobenzenethiol (2a; 0.34 g, 2.35 mmol, 2 equiv), were placed into a two-neck round-bottom flask equipped with dry ice condenser under inert atmosphere. Sulfur dioxide (35 ± 5 mL) was condensed into the flask at –78 °C. The resulting reaction mixture was allowed to warm up to the boiling point of SO2 (–10 °C), and the reaction was performed in liquid SO2 under the same temperature for 5 h. Then the flask was connected to SO2-collecting vessel cooled at –78 °C, and the excess of SO2 was transferred. The solid residue was purified by column chromatography (4% EtOH–CH2Cl2) and (R)-2-amino-3-[(4-chlorophenyl)thio]propanamide (3a, 149 mg, 55%) was obtained as an amorphous powder; [α]D 25 –53.5 (c 1.0, CHCl3).

- 29 General Procedure for Aziridine Ring Opening at 25 °C 1-(Aziridin-2-ylmethyl)-4-[4-(trifluoromethyl)phenyl]-1H-1,2,3-triazole (6; 0.05 g, 0.19 mmol, 1 equiv) and dodecane-1-thiol (2b; 89 μL, 0.37 mmol, 2 equiv) were placed into a stainless steel vessel. Three vacuum/nitrogen cycles were accomplished via Schlenk line. Sulfur dioxide (25 ± 2 g) was transferred into the vessel at –78 °C. Reaction was carried out under pressure (4 bar) at 25 °C for 14 h. Then the SO2-collecting vessel was cooled to –78 °C, connected to the reaction vessel, and the excess of SO2 was transferred. The resulting residue was purified by column chromatography (3% EtOH–CH2Cl2), and compound 9b (83 mg, 95%) was obtained as an amorphous powder.
