Abstract
In the title compound, 3,20-dihydroxycevan-6-one, C27H43NO3, all the six-me
mbered rings have normal chair conformations except ring D, which exists in
a twist-chair conformation. The five-membered ring C adopts an envelope co
nformation. An O-H . . .O hydrogen bond connects the molecules into spirals
, which run along the b-axis direction.
