Abstract
Procédé de préparation d'une aminolactone de formule (I) dans lequel : a 1) on réduit un composé de formule générale (III) où R représente un groupe alcoyle en C1 à C6, pour donner un composé de formule générale (II): où R a la meme signification que ci-dessus, on traite ce dernier composé en présence d'un acide alcanecarboxylique ayant une chaine alcoyle inférieure dans la fraction alcoyle, avec un hydrure complexe puis avec de l'acide chlorhydrique aqueux concentré et on recueille l'aminolactone; ou a 2) on traite un composé de formule générale (II) où R a la meme signification que ci-dessus, en présence d'un acide alcanecarboxylique ayant une chaine alcoyle inférieure dans la fraction alcane, avec un hydrure complexe puis avec de l'acide chlorhydrique aqueux concentré, et on recueille l'aminolactone.
