Crystal Structure and Synthesis of 3β-Acetoxy-4,16-pregnadiene-6,20-dione

Abstract

C₂₃H₃₀O₄ is orthorhombic, P2₁2₁2₁. The unit-cell dimensions at 293 K are a = 6.0490(3), b = 12.7788(7), c = 26.8859(15)Å, V = 2078.25(19)ų, D_x = 1.184 g/cm³, and Z = 4. The R value is R = 0.050 for 3663 reflections. The A, B, C and D rings occur in distorted half chair, distorted chair, distorted chair, and distorted envelope conformations. The molecules in the crystal are packed at the normal van der Waals distances.
