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

摘要

Methyl 12-bromo-13,14-furoxan-deisopropyldehydroabietate, C_(18)H_(22)BrN_2O_4, has been synthesized and characterized by 1R, ~1H NMR, ~(13)C NMR and single-crystal X-ray diffraction method. It crystallizes in orthorhombic, space group P2_12_12_1 with a = 6.652(2), b = 12.832(4), c = 20.483(6) A, V = 1748.5(9) A~3, Z = 4, M_r = 410.29, D_c = 1.559 g/cm~3, λ = 0.71070 A, 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.
