3,4-Difluoro-1-t-butyl-pyrrole was synthesized by the thermal [2+3] cycloaddition of 2-carbomethoxy-1-t-butyl-aziridine with chlorotrifluoro- ethylene, followed by treatment with sodium methoxide then with alcoholic potassium hydroxide. Thermal decarboxylation afforded the title compound.
3,4-二氟-1-叔丁基-吡咯是通过将2-羰基甲氧基-1-叔丁基-氮丙啶与三氟氯乙烯热[2 + 3]环加成,然后先用甲醇钠然后用醇处理而合成的氢氧化钾。热脱羧得到标题化合物。
