Nitro-olefins bicycloannulate the α'-enolates of α-cyclohexenones and α-cyclopentenones by initial addition at -78 deg C, followed by further reaction in situ in the presence of hexamethylphosphoramide in refluxing tetrahydrofuran to give tricyclo3.2.1.0

C13H19NO3, monoclinic, P21, a=8.881 (2), b=9.408 (2), c=8.481 (2) Angstroem, β=111.10 (1) deg, Z=2, Dc=1.19, Dm=1.18 (1) Mg m-3, U=661.1 Angstroem3, μ(Mo Kα)=4.9 mm-1.The final R1 and R2 values are 0.0421 and 0.0408 respectively, based on 1236 reflections for which F2>2?(F2).All 19 H atoms have been refined with isotropic Debye factors.The absolute configuration at C(11) has been shown to be R, based upon the known absolute configuration of (-)-carvone.
