Some spiro-heterocycles compounds have been synthesized by the piperidone hydrochloride, glycerol, aromatic acid, nicotinic acid and pyrazole acid. The target compounds were characterized by spectral data, including 1H and 13C NMR, infrared, elemental analysis and mass spectra and were bioassayed in vitro against two kinds of phytopathogenic fungi i.e., B. cinerea and R. solani. The results showed that some of the synthesized spiro-heterocycles derivatives exhibited moderate antifungal activities, among which compounds b, e, h, j, k and q displayed more than 80 % inhibition activities against B. Cinerea. at 50 μg/mL, which was better than that of the commercial fungicides spiroxamine and hymexazol.
一些螺吡咯烷异环化合物是通过盐酸哌啶酮、甘油、芳香酸、烟酸和吡唑酸合成的。目标化合物通过谱学数据进行表征,包括1H和13C核磁共振、红外光谱、元素分析和质谱,并在体外进行生物活性测定,针对两种植物病原真菌,即灰霉病菌(B. cinerea)和根腐病菌(R. solani)。结果表明,一些合成的螺吡咯烷衍生物表现出中等的抗真菌活性,其中化合物b、e、h、j、k和q在50 μg/mL的浓度下对B. cinerea的抑制活性超过80%,优于商业农药螺氟菌胺和氢氟乙酸。
