title: Ethyl 3-hydr-oxy-13-methyl-4'-phenyl-2'-(3,4,5-trimethoxy-phen-yl)-6,7,8,9,11,12,13,14,15,16-deca-hydro-spiro-[cyclo-penta-[a]phenanthrene-16,3'-pyrrolidine]-5'-carboxyl-ate.
abstract: In the title compound, C(39)H(45)NO(7),the pyrrolidine ring is connected to an estrone group, a trimeth-oxy benzene and a phenyl ring. The pyrrolidine ring exhibits a twist conformation and the other five-membered ring an envelope conformation. Mol-ecules are linked by N-H⋯O hydrogen bonds, C-H⋯π inter-actions and C-H⋯O hydrogen bonds.
