The title compound, spiro[1-bromo(S)-4-(R)-hydroxy-5-oxa-6-oxo-bicyclo[3.1.0]-hxane-2,2'-(3'-diethyl-α-(S)-4''-Cl-benzyloxyphosphonyl-4'-(1R,2S,5R)-menthyloxybutyrolactone)] has been synthesized via the tandem asymmetric reaction and it crystallizes in a monoclinic system, space group P21 with a = 11.067(3), b = 12.484(2), c = 12.356(2)(A), β = 101.95°,C29H39BrC1O10P, Mr = 693.93, V= 1670.2(6) (A)3, Z= 2, Dc= 1.380 g/cm3, λ(MoKα) = 0.071073nm, μ = 1.410 mm-1, F(000) = 720, the final R = 0.0570 and wR = 0.0758 for 6190 observed reflections with I ＞ 2σ(I). The structure is characterized by the special combination of biologic phosphonyl group and one cyclopropane as well as two butyrolactones. The intermolecular hydrogen bond between O(3)-H(3A)…O(10) in the crystal lattice has been observed.
