実験手順

Under a nitrogen atmosphere 500 mg (2.6 mmol) 5-(methylsulphanyl)-indole (Yang et al., Heterocycles, 1992, vol. 34, No. 6, page 1169-1175) are dissolved in 6 ml DMF and combined with 357 mg (3.2 mmol) potassium-tert-butoxide with stirring and cooling with ice. Then the mixture is stirred for 10 minutes at 0° C. 768 mg (2.9 mmol) N-tert-butoxycarbonyl-4,4-dimethyl-[1,2,3]oxathiazinane-2,2-dioxide (Component XI) are added. The mixture is then stirred for three hours at ambient temperature. Then the reaction solution is poured onto water and hydrochloric acid (1.2 mmol) and extracted with ethyl acetate. The organic phases are combined, dried on sodium sulphate and freed from the solvent in vacuo.
