Article abstract of DOI:10.1007/BF00899676

The interaction of 1-chlorodi-isophor-2(7)-en-3-one or its 5,11-bisnor-homologue with potassium phthalimide yields the corresponding 1-phthalimido-compounds, which are converted into the 1-amines on treatment with hydrazine, followed by hydrolysis. 1-Aminodi-isophor-2(7)-ene is not accessible by this route, but its N-acyl-derivatives are obtainable directly from 1-hydroxydi-isophor-2(7)-ene by the Ritter reaction; the 3-keto-analogue reacts similarly.Some properties of the novel 1-aminodi-isophoranes are described. - Keywords: Di-isophorones, 1-amino; Tricyclo<7.3.1.0^2,7>tridecanes
