Synthesis and Crystal Structure of Methyl 12-Bromo-13,14-furoxan-deisopropyldehydroabietate

【Abstract】 Methyl 12-bromo-13,14-furoxan-deisopropyldehydroabietate, C18H22BrN2O4, has been synthesized and characterized by IR, 1H NMR, 13C NMR and single-crystal X-ray diffraction method. It crystallizes in orthorhombic, space group P212121 with a = 6.652(2), b = 12.832(4), c = 20.483(6) , V = 1748.5(9) 3, Z = 4, Mr = 410.29, Dc = 1.559 g/cm3, λ = 0.71070 , μ(MoKα) = 2.377 mm-1, F(000) = 844, the final R = 0.0243 and wR = 0.0533 for 3780 observed reflections with I > 2σ(I). The C–H and bromine atom are involved in intermolecular hydrogen bonds which link the molecules into a one-dimensional chain.更多还原
