product of a Mannich reaction on butane-2,3-dione depended upon the secondary base employed. With dimethylamine the product was 2,4-bisdimethylaminomethyl-2-methylfuran-3(2H)-one (II). With morpholine or N-methylpiperazine, a bis Mannich base derived from 2,5-dimethylbenzene-1,4-diol was obtained while pyrrolidine was the only base investigated which gave the expected open chain bis Mannich derivative
曼尼希在2,3-丁烷上的反应产物取决于所用的仲碱。与二甲胺一起,产物为2,4-双二甲基氨基甲基-2-甲基呋喃-3(2 H)-一(II)。用吗啉或N-甲基哌嗪,得到了衍生自2,5-二甲基苯-1,4-二醇的双曼尼希碱,而吡咯烷是唯一研究得到预期的开链双曼尼希衍生物的碱。
