Abstract

Sulfamic esters of the general type R[sbnd]O[sbnd]SO2[sbnd]NH2 were alkylated under solid-liquid, liquid-liquid phase transfer catalysis conditions and by noncatalytic procedure, in homogeneous medium, in the presence of an equimolar amount of triethylamine, by means of a 1-adamantyl bromomethyl ketone. According to the procedure and the nature of R, these reactions yield the N-monoalkyl, N-dialkyl derivatives or a cleavage of the O[sbnd]SO2 bond with formation of the O-alkylation products.

Nous decrivons l'alkylation des esters sulfamiques de formule générale R[sbnd]O[sbnd]SO2[sbnd]NH2 au moyen de l'adamantyl-1 bromométhyl-cétone, en catalyse par transfert de phase solide-liquide, liquide-liquide et dans les conditions non-catalytiques, en phase homogène et en présence d'une quantité équimoléculaire de triéthylamine. Selon la méthode utilisée et la nature du radical R. on aboutit à des dérivés N-monoalkylés, N-dialkylés ou à la scission de la liaison O[sbnd]SO2 avec formation de produits de O-alkylation.
