Abstract

Une méthode de contraction de cycles est appliquée à la préparation de dérivés de cyclopentane, notamment d'acide 2,2,5,5-tétraméthylcyclopentanecarboxylique à partir de composés de cyclohexane. Dans un aspect, une diazocétone de cyclohexane est mise en réaction avec une amine (par exemple un ester d'alanine) pour former l'amide correspondant d'acide de cyclopentane.
