Alkyl 2-cyano-3-methylthio-3-phosphonylacrylates were synthesized by the reaction of alkyl 2-cyano-3,3-dimethylthioacrylates with dialkyl phosphites. The structures of the new compounds were characterized by elemental analyses, IR, 1H-, 13C- and 31P-NMR spectral data. These compounds were tested in vitro against pathogenic fungi, namely, Fusarium graminearum, Cytospora mandshurica and Fusarium oxysporum. Amongst all compounds, 2d and 2t were found to be effective against the tested fungi at 50μg/mL. A half-leaf method was used to determine the in vivo protective, inactivation and curative efficacies of the title products against tobacco mosaic virus (TMV). Title compounds 2a and 2b were found to possess good in vivo curative, protection and inactivation effects against TMV with inhibitory rates at 500 mg/L of 60.0, 89.4 and 56.5 and 64.2, 84.2 and 61.2 %, respectively. To the best of our knowledge, this is the first report on the antiviral and antifungal activity of alkyl 2-cyano-3-methylthio-3-phosphonylacrylates.
烷基2-氰基-3-甲基硫代-3-膦酰基丙烯酸酯通过烷基2-氰基-3,3-二甲基硫代丙烯酸酯与二烷基亚磷酸酯反应合成。新化合物的结构通过元素分析、IR、1H-、13C-和31P-NMR光谱数据表征。这些化合物在体外对病原真菌,即禾赤色镰孢、山里白棒孢和尖孢镰刀菌进行测试。在所有化合物中,2d和2t在50μg/mL时对测试的真菌有效。半叶法用于测定标题化合物对烟草花叶病毒(TMV)的田间保护、失活和治疗效果。标题化合物2a和2b被发现对TMV具有良好的田间治疗、保护和失活效果,抑制率在500 mg/L时分别为60.0、89.4和56.5以及64.2、84.2和61.2%。据我们所知,这是关于烷基2-氰基-3-甲基硫代-3-膦酰基丙烯酸酯抗病毒和抗真菌活性的首次报道。
