실험 절차

To a solution of 220 mg (1.2 mmoles) of 2,3-dichloro-4-nitropyrrole (pyrrolomycin A) in 10 ml of dry N,N-dimethylformamide were added 606 ml (1 mmole) of 2,3,3-triiodoallyl-p-toluenesulfonate and 0.14 ml (1 mmole) of triethylamine and the resulting mixture was heated at 60° C. for 30 minutes. After cooling, 20 ml of cold water were added dropwise with stirring to the reaction mixture and stirring was continued for a further one hour. The so separated crystalline substance, 1-(2',3',3'-triiodoallyl)-2,3-dichloro-4-nitropyrrole, was recovered by filtration, washed with water and then dried. Yield 567 mg (95%), mp 126°-127° C.
