(11R,13R)-13-(Tetra­lin-1-ylamino)-4,5-ep­oxy-11,13-dihydro­costunolide

Abstract

The title compound [systematic name: (12R)-4,8-dimethyl-12-[(1′R)-1′,2′,3′,4′-tetrahydro-1′-naphthyl)aminomethyl]-3,14-dioxatricyclo[9.3.0.02,4]tetradec-7-en-13-one}, C25H33NO3, was formed from the reaction of (1R)-1-amino­tetra­lin with parthenolide in methano­lic solution. X-ray crystal structure analysis determined that the configuration of the new chiral center in the title compound was R.

Comment

Due to the interesting biological activity of parthenolide, we have synthesized a series of amino analogs of parthenolide (Crooks et al., 2005). In order to confirm the configuration of the newly formed methine carbon at C-11 in these molecules, and to obtain more detailed information on the structural conformation of the molecule that may be of value in structure activity relationship studies, the X-ray structure determination of the title compound has been carried out and the results are presented below. The absolute stereochemistry of the newly formed methine at C-11 was found to be R, which is typical in structurally related C-11 aminoparthenolide analogs that result from the reaction of an secondary amino compound with parthenolide (Nasim et al., 2007a, 2007b). Bond distances and angles within the molecule were quite regular with normal bond lengths (Allen et al., 1987). A hydrogen bond is observed between N-1H and O3 of the carbonyl oxygen of the 5-membered lactone ring (Desiraju et al.,1999) (2.32 (3) A°, 2.99 (2) A°, 123.5 (18)°) (Table 1).

Experimental

The title compound was prepared utilizing the general procedure reported earlier (Nasim et al., 2007a, 2007b).

Refinement

H atoms were found in difference Fourier maps and subsequently placed in idealized positions with constrained C—H distances of 0.95Å (Csp2—H), 1.00Å (R3CH), 0.99Å (R2CH2), 0.98Å (RCH3) except for the NH hydrogen coordinates, which were refined. Uiso(H) values were set to 1.2Ueq or 1.5Ueq (RCH3 only) of the attached atom.

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.
