3-AMINO-2-CYCLOHEXEN-1-ONE Chemical Properties,Uses,Production

Chemical Properties

Dark yellow crystal

Uses

3-Amino-2-cyclohexen-1-one was used in the synthesis of a series of 2-amino-5-oxo-4-phenyl-5,6,7,8-tetrahydroquinoline-3-carbonitriles.

Synthesis

504-02-9

5220-49-5

General procedure for the synthesis of 3-amino-2-cyclohexen-1-one from 1,3-cyclohexanedione: 1,3-cyclohexanedione (0.03 mol) and ammonium acetate (0.039 mol) were added to a 100 mL three-necked flask, and the mixture was thoroughly stirred. The mixture was placed in an oil bath at 110°C for 15 min of reaction. Upon completion of the reaction, the oil bath was removed and the reaction system was allowed to cool naturally, at which time the reaction solution gradually solidified. After cooling to room temperature, ethyl acetate (10 mL) was added to the reaction mixture and heated to dissolve the solid, which was subsequently cooled to 0°C to promote crystallization. The precipitated solid was collected by filtration and dried to give yellow crystals of 3-amino-2-cyclohexen-1-one in 93.6% yield.
