This invention relates to a fluorinated taxol of formula I
in which
R¹ is-CORz in which Rz is RO- or R;
Rg isC₁₋₆ alkyl, C₂₋₆ alkenyl, C₂₋₆ alkynyl, C₃₋₆ cycloalkyl, or a radical of the formula -W-Rx in which W is a bond, C₂₋₆ alkenediyl, or -(CH₂)t-, in which t is one to six; and Rx is naphthyl, furyl, thienyl or phenyl, and furthermore Rx can be optionally substituted with one to three same or different C₁₋₆ alkyl, C₁₋₆ alkoxy, halogen or -CF₃ groups;
R² is-OCOR, H, OH, -OR, -OSO₂R, -OCONRoR, -OCONHR, -OCOO(CH₂)tR, or -OCOOR; and
R and Roare independently C₁₋₆ alkyl, C₂₋₆ alkenyl, C₃₋₆ cycloalkyl, C₂₋₆ alkynyl, or phenyl, optionally substituted with one to three same or different C₁₋₆ alkyl, C₁₋₆ alkoxy, halogen or -CF₃ groups.
Further provided by this invention are pharmaceutical formulations and useful intermediates for the fluorinated taxols of formula I. A method of treating mammalian tumors using a compound of formula I is also provided.
