Abstract

L'invention concerne un procédé permettant de préparer des produits de condensation à partir d'alcanoyl-acétates d'alkyles inférieurs et d'aldéhydes. Ce procédé est caractérisé en ce qu'on effectue la condensation en présence d'une amine aliphatique tertiaire, telle que la triméthylamine, la triéthylamine ou la triéthanolamine. On peut ainsi obtenir, par exemple, des oxy-cyclohexanols ou des cyclohexénones, qui, en raison de leurs divers groupes réactifs, sont des corps intermédiaires aux applications variées.
