The new unexpected products during heteroannulation of 1, 4-naphthoquinone derivatives were investigated. A series of substituted heterocyclic 1, 4-naphthoquinones were also synthesized. The removal of acetic anhydride under reduced pressure was also studied. A stirred suspension of 2-(carboxymethyl-amino)-1, 4-naphthoquinone14 (0.01 mole) in a mixture of azobenzene (0.01 mole) and chlorobenzene (100 mL) was heated to reflux in an oil bath maintained at 150-160°C for 10 hours.
