7α-Methoxy-carbonyl-6,7,8,14-tetrahydro-6,14-endo-ethenothebaine

Abstract

In the mol-ecule of the title compound, C<inf>23</inf>H<inf>27</inf>NO <inf>5</inf>, the furan ring adopts an envelope conformation. Intra-molecular C - H⋯O inter-actions result in the formation of S(5) and S(6) motifs. In the crystal structure, weak inter-molecular C - H⋯O hydrogen bonds link the mol-ecules through C(6) and C(8) chains along the [100] and [010] directions, generating a two-dimensional network.
