In general formulae (I) and (II), Ar is an aryl radical; R.sub.1 and R.sub.2 which are the same or different, are a hydrogen atom, an alkyl, phenylalkyl, phenyl, alkoxyphenyl or dialkoxyphenyl radical, or R.sub.1 or R.sub.2, together with the carbon atom to which they are attached, form a 4-7 membered ring; R.sub.3 is an acetyl radical or a hydroxy function protective grouping, and R.sub.4 is a hydroxy function protective grouping; R is a phenyl radical or a radical of formula R.sub.5 --O-- wherein R.sub.5 -- is an alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, phenyl or saturated or unsaturated nitrogenous heterocylcyl radical. The products of general formula (I) are particularly useful for preparing taxol, Taxotere and analogues thereof having remarkable antitumor properties. ##STR1##

    摘要: The invention concerns the preparation of nothapodytine or camptothecin derivatives which consists in causing 4-ethyl 2methyl hepta-2,4-dienoic acid act on a 3-aminomethyl 2-bromo quinoline derivative (III) wherein R1 and R2 are H or R1 is a halogen atom or alkyl, R2 is a O—CO—X radical as defined for the camptothecin derivatives; or R1 and R2 are defined for the known camptothecin derivatives or represent protected radicals or radicals easily convertible into the radicals R1 and R2, to obtain the quinoline derivative (IV); adding to the resulting quinoline derivative (2-methoxy carbonyl vinyl) tributyltin in the presence of a complex of palladium and triphenylarsin to obtain the quinoline derivative (V); cyclizing the resulting quinoline derivative to obtain the tetracyclic derivative (VI); then in subjecting said derivative to an ozonolysis followed by treatment with dimethyl sulphide to obtain the tetracyclic derivative (VII); saponification followed by decarboxylation in oxidising conditions of the resulting tetracyclic derivative to obtain the nothopodytine derivative (VIII); then optionally transforming the resulting derivative into a camptothecin derivative or into a mappicine derivative.
