Abstract

992,796. 3 - alkoxy - 6 - oxo - N - alkyl- C-normorphinans. SHIONOGI & CO. Ltd. April 4, 1963 [April 6, 1962], No. 13481/63. Heading C2C. The invention comprises compounds of the plane formula where R represents an alkyl group having not more than 5 carbon atoms, R<SP>1</SP> represents a hydrogen atom or an aryloxy group and R<SP>11</SP> represents an alkyl group having not more than five carbon atoms, and the preparation thereof by reacting a compound of the plane formula with hydrogen peroxide in an inert organic solvent medium and heating the thus produced compound of the plane formula with an alkanoic anhydride in which the alkyl moiety has not more than three carbon atoms. Both stages of the process are preferably carried out under reflex. The dehydrating agent may be used as the solvent medium in the second stage of the process and it is preferred that during the course of the dehydration fresh dehydrating agent is added to or substituted for the primarily employed agent. Specification 992,767 is referred to.
