Abstract
The title compound, C25H31NO2.H2O, has the outer two six-membered rings in chair conformations, while the central ring is in an 8 beta ,9 alpha -half- chair conformation. The five-membered ring adopts a 13,14-half-chair confor mation. The pyridyl-methylene moiety has an E configuration with respect to the carbonyl group at position 17. The structure is stabilized by intermol ecular O-H . . .N and O-H . . .O hydrogen bonds.
