Synthesis and Characterization of New Cyclic Aminobenzoquinones

Abstract

The aim of this research is to synthesize and characterize of new cyclic members of cyclic aminobenzoquinones. Mono amino substituted products; 2-chloro-5,6-dimethyl-3-(pyrrolidin-1-yl)-1,4-benzoquinone (2), 2-chloro-5,6-dimethyl-3-(piperidin-1-yl)-1,4-benzoquinone (3), 2-chloro-5,6-dimethyl-3-morpholino-1,4-benzoquinone (4), and 2-chloro-5,6-dimethyl-3-thiomorpholino-1,4-benzoquinone (5) have been synthesized by a green methodology using water as solvent by means of nucleophilic substitution reactions between 2,3-dichloro-5,6-dimethyl-1,4-benzoquinone (1) and cyclic secondary amines. Structure determination of the new products (2-5) was established on the basis of IR, ¹H NMR, ¹³C NMR, and mass spectrometry.
