Yuzurimine from of Daphniphyllum macropodum Miq.

Abstract

The title compound, C₂₇H₃₇NO₇, is a Daphniphyllum alkaloid isolated from a branch of Daphniphyllum macropodum Miq. All of the five-membered rings adopt envelope conformations while the six- and seven-membered ring adopt chair conformations. Classical inter­molecular O—H⋯O and weak C—H⋯N hydrogen bonds are present in the crystal structure.

Comment

The title compound, yuzurimine, was previously isolated from Daphniphyllum macropodum Miq. (Li et al. 2009), and its structure was established from the NMR and MS data. In our recent investigation, it was isolation from the branch of Daphniphyllum macropodum Miq. collected in the Emei Mountain, Sichuan Province of China in 2008. Its crystal structure is reported here.

The molecular structure of the title compound is shown in Fig. 1. Six-membered ring A (C1/C2/C3/C4/C5/C8) adopts chair conformation; Six-membered heterocyclic ring B (C1/N1/C7/C6/C5/C8) displays the same chair conformation; seven-membered ring C (C5/C6/C12/C11/C10/C9/C8) adopts a screw-chair conformation; five-membered rings D (C8/C9/C13/C14/C15) and E (C10/C9/C15/C16/C17) adopt an envelope conformations. While the five-membered heterocyclic F (C1/N1/C19/C18/C2) displays an envelope conformation.

Experimental

The title compound was isolated from the branch of Daphniphyllum macropodum Miq. And crystals suitable for X-ray structure analysis was obtained by slow evaporation from an acetone solution at room temperature.

Refinement

H atoms were located geometrically with C—H distance of 0.93–0.98 Å, and refined using a riding model with U_iso(H) = 1.2 U_eq(C). As no significant anomalous scatterings, Friedel pairs were merged.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
