摘要

1, 4, 4-Trialkylpyrrolidine-2, 3, 5-triones (I) of proved structure have not been reported. 1, 4- Di-phenyl-4-ethylpyrrolidine-2, 3, 5-trione1 was prepared incidentally from the corresponding oxazolidinedione (11) due to the fact that the latter had been crystallized from ethyl alcohol, a procedure which results in the rearrangement of I1 to the trialkylpyrrolidinetrione. The previously prepared pyrrolidinetriones2 bearing a hydrogen ...
