Abstract EN

In this work we synthesized a new piperidone compound 1-propyl -3a-methyl - 3e - hydroxy - 6e - (2 - benzeyloxyphenyl) piperidone - 4 (II) and some of its derivatives which many have effective biological importance, described methods of synthesis of these compounds and identified their structure and physical constants.

The prepared derivatives are: 1-propyl-3a-methyl-3e-hydroxy - 6 - (2 - benzeyloxyphenyl) piperidone oxime - 4 (III) and 1-propyl-3a - methyl - 3e, 4e - dihydroxy - 6 - (2 - benzeyloxyphenyl) piperidine (IV), and 1-propyl - 3a - methyl- 3e - hydroxy - 6 - (2 - benzeyloxyphenyl) piperidone thiosemicarbazone (V).

The infrared (IR), nuclear magnetic resonance (1H-NMR, 13C- NMR) and mass (MS) spectrum of these compounds were studied.
