(EN) This invention relates to a taxoid of formula (I), wherein R1 is a C3-C5 alkyl or alkenyl radical; R2 is a C3-C5 branched alkyl radical; R3 and R4 are independently selected from hydrogen and hydroxyl protecting groups including functional groups which increase the water solubility of the taxoid antitumor agent; R5 is a hydrogen, an acyl radical, or an alkoxylcarbonyl or carbamoyl radical; and R6 is an acyl radical. The compounds of formula (I) are useful as antitumor agents or their precursors. This invention also relates to a pharmaceutical composition having antineoplastic activity comprising the compound of formula (I) and a physiologically acceptable carrier and method of treatment using the compound of formula (I).(FR) L'invention concerne un taxoïde de formule (I), dans laquelle, R1 est un radical alcényle ou alkyle C3-C5; R2 est un radical alkyle ramifié C3-C5; R3 et R4 sont indépendamment choisis parmi les groupes de protection hydrogène et hydroxyle comprenant des groupes fonctionnels qui augmentent l'hydrosolubilité du taxoïde antitumoral; R5 est un hydrogène, un radical acyle ou un radical alcoxycarbonyle ou carbamoyle; et R6 un radical acyle. Les composés de formule I sont utiles en tant qu'agents antitumoraux ou leurs précurseurs. L'invention porte également sur une composition pharmaceutique à activité antinéoplasique, comprenant le composé de formule (I) et un vecteur physiologiquement acceptable ainsi qu'un procédé de traitement dans lequel le composé de formule (I) est utilisé.

Acid chlorides, complexed with excess aluminiumchloride, reacted with ethene to form 3-methyl-2-buten-1-ones, i.e. rearranged di-addition products having a terminal isoprenoid skeleton, together with the usual β-chloropropanones. The latter were the sole products in the absence of excess catalyst. Acid chlorides containing a suitably situated π-system underwent intramolecular cyclization, e.g. 2-
