Fg. Moers et al., CRYSTAL AND MOLECULAR-STRUCTURE OF LENE]-3,3A,4,8B-TETRAHYDROINDENO[1,2-B]FURAN-2-ONE, Journal of chemical crystallography, 25(7), 1995, pp. 429-432
The stereogeometry and absolute configuration of the title compound ha
s been proved by an X-ray diffraction analysis. Crystal data: monoclin
ic, C2, a = 20.2528(4), b = 6.7254(2), c = 10.6748(2) Angstrom, beta =
94.699(3), Z = 4. The crystal structure has been solved by vector sea
rch methods and refined to R(1) = 0.053 for 2043 observed reflections.
