Abstract
(EN)
The invention concerns a new process for preparing delmopinol using intermediates having formula (A) wherein R is 2-propylpentyl optionally with one, two or three internal unsaturated bonds, or 2-substituted-2-propylpentyl optionally with one or two internal unsaturated bonds wherein the 2-substituent is a leaving group.

(FR)
L'invention concerne un nouveau procédé de préparation de delmopinole au moyen d'intermédiaires dont la formule est (A) où R représente le 2-propylpentyle ayant un, deux ou trois liens désaturés internes au choix, ou le 2-substitué-2-propylpentyle ayant un ou deux liens désaturés internes au choix où le 2-substituant est un groupe de sortie.
