Solvent-and Catalyst-free Synthesis and Antifungal Activities of α-Aminophosphonate Containing Cyclo

Nine new α-aminophosphonate derivatives containing cyclopropane moiety have been synthesized via conventional and microwave irradiation methods under solvent-and catalyst-free condition.The structures of the title compounds have been confirmed by 1H NMR,31P NMR,FTIR,EI-MS and FTICR-MS.Their antifungal activities were evaluated in vivo and some of the compounds were found to exhibit excellent antifungal activities against Corynespora cassiicola,Pseudomonas syringae pv.Lachrymans,Pseudoperonospora cubensis and Sclerotinia sclerotiorum.
