Degradation of atorvastatin: (1R,2S,4S,5S)-4-(4-fluoro-phen-yl)-2-hydro-peroxy-4-hydr-oxy-2-isopropyl-N,5-diphenyl-3,6-dioxabicyclo-[3.1.0]hexane-1-carboxamide.

Abstract

The degradation of atorvastatin calcium in methanol and hydrogen peroxide results in the crystallization of the title compound, C(26)H(24)FNO(6), which shows several differences compared with the starting compound. In the crystal structure of the title compound, intra- and inter-molecular hydrogen bonding is found.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles
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.
