    Nitration of cis-β-(2-furyl) acrylic acid afforded the corresponding cis-β-(5-nitro-furyl), acrylic acid. It was readily converted to cis-β-(5-nitro-2-furyl)-N-isopropyl-acrylamide by amination with isopropylamine through the mixed anhydride method.The biological activity of this cis-isomer was examined in laboratory animals against experimental schistosomiasis and was shown to possess activity similar to that already reported for the trans-isomer.

    Amiprophos-M, ethyl 2-nitro-4-methylphenyl N-isopropyl phosphoramidothionate, crystallizes in the triclinic space group P1 with two molecules in the unit cell. The crystallography parameters are: a=8.636 (1), b=10.483 (2),c=10.694(2) A; a=110.92(1)°, β=111.27(1)°, γ=98.97(1)°;V=796.2(3)A~3; D_c=1.33g/cm~3; F(000)=336;(MoK_α)=3.2cm~(-1). The crystal structure has been solved by the direct method and refined by the block-diagonal least-squares procedures to final R values of R_1=0.055 and R_2=0.047. The phosphorus atom of the Amiprophos molecule forms four tetrahedral covalent bends, of which the P-S bond exhibits rather high double bond character. It implies that the empty 3d-orbital of the phosphorus atom should be involved in the chemical bond formation.

    胺草磷晶体,属三斜晶系,空间群为C_i~1-PI,晶胞中含两个分子,晶体学数据为:a=8.636(1),b=10.483(2),c=10.694(2)(?);α=110.92(1)°,β=111.27(1)°,γ=98.97(1)°;V=796.2(3)(?)~3,D_c=1.33g/cm~3,F(000)=336;μ(MoK_α)=3.2cm~(-1)。此结构用直接法解出,最后的R因子为:R_1=O.055,R_2=0.047。胺草磷分子中的磷原子形成四个四面体向的化学键,其中P—S键含有相当高的双键成分,这意味着磷原子的3d轨函参与成键。
