摘要

Fluorinated catharanthine derivatives (I) are new. Fluorinated catharanthine derivatives of formula (I) are new. X : OR, NR'R", SR or halo, or is absent when the dotted line denotes a double bond; R, R', R" : H or 1-6C alkyl; R1, R2, R3H, F or Me, provided that R1 and/or R2 is F; n : 1 or 2. An independent claim is also included for a process for preparing (I). [Image].
