Towards validating new enzymatic routes for synthetic conversion: 7,10‐bis‐O‐(2,2,2‐trichloroethoxycarbonyl)‐10‐deacetyl baccatin III–ethyl acetate–water (1/1/1)

The title compound, C₃₄H₃₈Cl₆O₁₄·C₄H₈O₂·H₂O, prepared by the reaction of 10‐deacetyl baccatin III with 2,2,2‐trichloroethyl chloroformate in pyridine, crystallizes via strong intermolecular hydrogen bonds and noncovalent interactions between 7,10‐bis‐O‐(2,2,2‐trichloroethoxycarbonyl)‐10‐deacetyl baccatin III (7,10‐di‐Troc‐DAB), water and ethyl acetate. A detailed comparison of the molecular conformation with those of related structures is presented.
