Process for the preparation of 1,4-diazabicyclo[2.2.2]octanes

摘要

The invention relates to a process for the preparation of 1,4-diazabicyclo[2.2.2]octane and C-substituted 1,4-diazabicyclo[2.2.2]octanes of the formula (I) <IMAGE> in which R<1> and R<2> can denote hydrogen radicals, alkyl radicals having from 1 to 4 C atoms or alkenyl radicals having from 1 to 4 C atoms, by reacting heterocyclic amines of the formula (II) <IMAGE> in which R<1> and R<2> have the abovementioned meaning and R<3> denotes hydrogen, hydroxyethyl or aminoethyl radicals and X denotes hydroxyl, amino, hydroxyethyl or aminoethyl radicals, in the presence of L-zeolites as catalysts.
