Abstract:The X-ray crystal structure
of 3α,4α:5β,6β-diepoxyandrostan-17-one has been determined.
Crystals of the title compound (C19H26O3)are
monoclinic, space group P21, with a 9.208(2), b 9.620(4), c 9.312(3) �, β 99.14(2)�, V 814.5
Ǻ3 and Z 2. The structure was solved by direct methods and refined
to R 0.039 for 887 observed reflexions. The 3α,4α:5β,6β
configuration of the epoxide rings confirms the assignment based on proton
n.m.r. studies.
