presence of potassium t-butoxide to give the trans (SC4H3/CO2Me) half-ester (IIIa) whose configuration was deduced by cyclization to the corresponding benzo[b]thiophene derivatives. Carbamates, esters, cyclic hydrazides and substituted phenolic and acetic acids useful as antibacterial and antiinflamatory agents were obtained. The reaction of ketone I with malononitrile to give ylidenemalononitrile II was
在叔丁醇钾的存在下,将对甲苯基2-噻吩基酮(I)与琥珀酸二甲酯缩合,得到反式(SC 4 H 3 / CO 2 Me)半酯(IIIa),其构型可通过环化反应制得。相应的苯并[ b ]噻吩衍生物。获得了可用作抗菌剂和消炎剂的氨基甲酸酯,酯,环状酰肼和取代的酚酸和乙酸。还考虑了酮I与丙二腈的反应以得到亚甲基丙二腈II。
