DERIVATIVE OF 14-HYDROXYNJRMORPHINONE, DERIVATIVE OF MORPHINONE, DERIVATIVE OF MORPHINE, METHODS FOR PREPARING DERIVATIVE OF 14-HYDROXYNORMORPHINONE, DERIVATIVE OF MORPHINONE, NOROXYMORPHONE Russian patent published in 2007 - IPC C07D489/08 

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to compounds, namely, to derivative of 14-hydrxoynormorphinone of the formula (IV) , derivative of morphinone of the formula (III) , derivative of morphine of the formula (II) wherein R₁ represents (C₁-C₇)-alkyl; R₂ represents benzyl or benzyl substituted with one or some (C₁-C₆)-alkoxy-groups, or benzyl substituted with one or some halogen atom. Also, invention relates to a method for synthesis of derivative of 14-hydroxynormorphinone of the formula (IV) involving interaction of compound of the formula (III) with cobalt (II) as oxidant in the presence of a weak base and air or oxygen as co-oxidant. Also, invention relates to a method for synthesis of derivative of morphinone of the formula (III) involving interaction of derivative of morphine of the formula (II) with oxidizing agent that is effective in oxidation of allyl hydroxy-groups. Mainly, invention relates to a method for synthesis of noroxymorphone. The process involves oxidation of derivative of morphinone of the formula (III) to derivative of 14-hydroxynormorphinone of the formula (IV), removal of protection from 3-position and reduction of double bond at 7,8-position in derivative of 14-hydroxynormorphinone of the formula (IV) to yield derivative of 3,14-hydroxynormorphinone of the formula (V) and hydrolysis of derivative of 3,14-hydroxynormorphinone of the formula (V) to yield noroxymorphone of the formula (VI) wherein formulae (V) and (VI) are given in the invention description. Invention provides synthesis of noroxymorphone using novel intermediate compounds.

EFFECT: improved method of synthesis.
