With trimethylphenylammonium tribromide In water; acetonitrile at 28℃; for 12h; | 4.1. General procedure for sharpless aziridination General procedure: To a mixture of an appropriate olefin (3 mmol) and TsNClNa*3H2O (CAT) (0.930 g, 3.3 mmol) in CH3CN (15 mL), was added phenyltrimethylammonium tribromide, (PTAB) (0.113 g, 0.3 mmol) at 28 °C. After 12 h of vigorous stirring, the reaction mixture was concentrated and filtered through a short column of silica gel and eluted with 10% EtOAc in hexanes. After evaporation of solvent, the resultant solid was purified by flash column chromatography to yield the corresponding aziridines in good yield. |

To this mixture was added Chloramine T trihydrate (14.05 g, 2.5 equiv.). The mixture was stirred overnight at room temperature. The reaction was then quenched by adding 100 mL DCM. The precipitate was filtered off and mixture concentrated to give crude product. The crude product was dissolved in ca. 500 mL of acetone and insoluble solid filtered off. The filtrate was placed at room temperature. meso ligand would precipitate out in one day or two. After the meso ligand was collected by filtration, the filtrate was then again placed at room temperature for the precipitation of racemic ligand. |

General experimental procedure for the reaction of chloramine T and arylboronic acid General procedure: A test tube with stir bar was charged with N-Chloro-N-sodiosulfonamide 2 (0.3 mmol), arylboronic acid 1 (0.36 mmol) and tBuOK (50.5 mg, 0.45 mmol). A solution of Cu(OAc)2 (2.7 mg,0.015 mmol) in EtOH (1.5 mL) was then added to the test tube. The reaction mixture was stirred under air at room temperature for 12 h, then the heterogeneous mixture was diluted with ethylacetate. The resulting mixture was directly filtered through a pad of silica gel, then the silica gelwas eluted with ethyl acetate. The organic solutions was combined, and the solvent was removedunder reduced pressure. The crude product was purified by silica-gel column chromatography toafford the desired product. |
