Synthesis of 2,7-Diazabicyclo[3.2.1]oct-3-ene Derivatives
摘要:
Tetracyanoethylene adducts with ketones, 4-oxoalkane-1,1,2,2-tetracarbonitriles reacted with hydrogen chloride or phosphorus(III) chloride in 1,4-dioxane to give 3-chloro-6-oxo-2,7-diazabicyclo[3.2.1]oct-3-ene-4,5-dicarbonitrile derivatives.
