Criss-cross cycloadditions on ketazines derived from alicyclic ketones

Abstract

The reactivity of alicyclic ketazines in criss-cross cycloadditions was investigated. They react with potassium cyanate and ammonium thiocyanate in the presence of acetic acid to form spirocyclic perhydro[1,2,4]triazolo[1,2-a][1,2, 4]triazole-1,5-diones and perhydro[1,2,4]triazolo[1,2-a][1,2,4]triazole-1,5- dithiones, respectively, in relatively high yields. © 2006 by MDPI.
