Reactions of 2-Acetyl-5-hydroxy-5-methyl3-phenylcyclohexanone and Alkyl 4-Hydroxy-4-methyl2-oxo-6- phenylcyclohexanecarboxylates with Nucleophilic Reagents

A series of novel enamines, bis(enamines), benzisoxazoles, tetrahydroindazoles, benzophenone hydrazones were obtained via reactions of 2-acetyl-5-hydroxy-5-methylcyclohexanone and alkyl 4-hydroxy-4-methyl2- oxocyclohexanecarboxylates with nucleophilic reagents such as aliphatic and aromatic amines, diamines, hydroxylamine, hydrazine, phenylhydrazine, benzophenone hydrazone. The structures of the compounds obtained were proved by IR and [sup.1]H NMR spectroscopy methods. Keywords: 2-acetylcyclohexanone, alkyl 2-oxocyclohexanecarboxylates, enamines, indazoles, benzisoxazoles, hydrazones DOI: 10.1134/S1070363219070016
