Structure-activity relationship studies were employed to synthesize a series of 3- and 3,4-substituted benzamides from 3-amino-2-cyclohexenones. An improved method for the synthesis of benzamides from 3-amino-2-cyclohexenones is presented which provided significantly higher yields (71-79%) for the reported compounds. NMR and X-ray structural analyses were undertaken to note the possible intra- and intermolecular

Abstract A novel copper(II) acetate mediated synthesis of 3-hydroxyphenanthridin-6(5H)-ones from N-(3-oxocyclohex-1-enyl)benzamides was developed. The process is postulated to involve an intramolecular oxidative C(sp2)–C(sp3) bond formation followed by dehydrogenative aromatization.

The Cul-catalyzed coupling reaction of vinyl halides with amides or carbamates proceeds well at room temperature to 80 degreesC in dioxane to give enamides using NN-dimethylglycine as the promoter and Cs2CO3 as the base. The geometry of the C-C double bond is retained during the reaction course.
