The title compound,(3R,4R)-4,7,7-trimethyl-6-oxabicyclo[3.2.1]octane-3,4-diol(C10H18O3),has been synthesized by using one-step catalytic synthetic method from a-pinene and structurally characterized by means of IR,~1H-NMR,13C-NMR,HRMS and single-crystal X-ray diffraction.The crystal belongs to the monoclinic system,space group P2_1/n with α = 7.277(4),b =18.177(11),c = 7.939(5) A,β = 91.122(8)°,Z = 4,V= 1049.9(11) A,D_c = 1.178 g/cm~3,Mr=186.24,λ(MoKα) = 0.71073 A,μ = 0.09 mm~(-1),F(000) = 408,R = 0.051 and wR = 0.144.The title complex molecules contained two hydroxyls and are connected through hydrogen bonds to generate a two-dimensional network.Especially,the preliminary herbicidal activity results show that the title compound exhibits herbicidal activity against rape(Brassica campestris) and barnyard grass(Echinochloa crusgalli).
The title compound, (3R, 4R) -4,7,7-trimethyl-6-oxabicyclo [3.2.1] octane-3,4- diol (C10H18O3), has been synthesized by using one-step catalytic synthetic method from a -pinene and structurally characterized by means of IR, ~ 1H-NMR, 13C-NMR, HRMS and single-crystal X-ray diffraction.
