摘要：
The title compound 4-(dichloroacetyl)-1-oxa-4-azaspiro[4. 5] decane (CAS number 71526-07-3, C10H15Cl2NO2, M-r = 252.13) was obtained by the reaction of dichloroacetic acid with 1-oxa-4-azaspiro[4. 5] decane. The crystal is of monoclinic, space group P2(1)/n with the unit cell constants: a = 5.9619(4), b = 10.0066(8), c = 20.0986(4) Angstrom, beta = 90.194(3)degrees, V = 1199(4) Angstrom(3), Z = 4, D-c = 1.397 g/cm(3), F(000) = 528, mu(MoKalpha) = 0.522 mm(-1), R = 0.0611 and wR = 0.1656 for 1276 observed reflections (I > 2sigma(I)). X-ray analysis reveals that the cyclohexyl adopts a chair conformation and the compound is a chiral one.
