Reaction Steps

Phosphazene base 1-tert-butyl-2,2,4,4,4-pentakis(dimethylamino)-2-lambda5-5,4-lambda5-5-catenadi(phosphazene) (P2-tBu) (2M in THF) (0.3 ml, 0.6 mmol) was added to a solution of 5,5-dimethyl-3-(1-phenyl-ethanesulfonyl)-4,5-dihydroisoxazole (150 mg, 0.56 mmol) in THF (8 ml) at room temperature. After 10 minutes N-fluorobenzene-sulfonimide (NFSI) (190 mg, 0.6 mmol) was added. The mixture was stirred at room temperature for 15 minutes. The mixture was absorbed onto silica gel and purified by chromatography on silica gel (eluent: ethyl acetate/hexane) to give the product (Compound No. 1.138 of Table 27) as a white solid (89 mg, yield 56%).
