Patent GB-859568-A (GB)
Title: 2-substituted-2,6-dimethyl octane derivatives
IPC: C07D303/08
Filed: 1957-04-03
Abstract: The invention comprises 2,6-dimethyloctane derivatives having the general formula :  <FORM:0859568/IV(b)/1> in which Y is the group <FORM:0859568/IV(b)/2> or the group <FORM:0859568/IV(b)/3> in which one group A is a hydroxyl radical and the other is a halogen radical, and x is a halogen, hydroxyl, alkoxy or acyloxy (derived from a carboxylic acid) group.  The compounds of the above formula in which Y is the group <FORM:0859568/IV(b)/4> may be prepared by (a) epoxidising a compound of formula :  <FORM:0859568/IV(b)/5> for example, by treating with a per-acid or with gaseous oxygen, or, by forming the corresponding halohydrin and submitting it to dehydrohalogenation ; and (b) if desired, when X is a halogen, alkoxy or acyloxy radical, hydrolysing it to convert it to a hydroxyl group. If desired the oxirane group may be thermally isomerised, preferably at a temperature above 200 DEG  C. to give the aldehyde group -CH2CHO.  When X is an acyloxy radical the hydrolysis is carried out in an acidic or basic medium ; when X is a halogen radical it is carried out in a basic medium and when X is alkoxy it is preferably carried out in an acidic medium.  The process is particularly suitable for producing 2-hydroxy-dihydrocitronellal from <FORM:0859568/IV(b)/6> by producing <FORM:0859568/IV(b)/7> and thermally isomerising it to the corresponding aldehyde.  Some citronellal may also be formed as a result of the heat treatment. The halohydrins may be obtained by treating the unsaturated starting compound with hypochlorous or hypobromous acid.  The chlorhydrin is converted to the corresponding epoxy compound by heating it with a base, e.g. caustic soda.  If the 2-substituent is a halide group, some dehydrohalogenation takes place resulting in the formation of the corresponding unsaturated compound.  The chlorhydrin can be converted to the aldehyde in one stage by heating it, preferably with a base, at a sufficiently high temperature.  If heated without a base until decomposition takes place 2-hydroxy-2,6-dimethyl-octane-7,8-chlorhydrin yields a mixture of 2,6-dimethyl-1-octen-8-al and 8-chlor-2,6-dimethyl-1,7-octadiene.  A small amount of 2-hydroxy-2,6-dimethyl-octane-7-one is also formed and this may be dehydrated to give the corresponding unsaturated ketone.  When 2,6-dimethyl-7-octene-2-ol is subjected to hypochlorination 7,8-dichlor-2,6-dimethyl-octane-2-ol is also formed. This may be dechlorinated by means of sodium and alcohol to give 2,6-dimethyl-7-octene-2-ol which may be recycled for subsequent hypochlorous acid treatment.  The 7,8-dichloro-2,6-dimethyl-octane-2-ol may be dehydrated to give 7,8-dichloro-2,6-dimethyl-2-octene.  The 7,8-dichloro-2,6-dimethyl-octane-2-ol may be dehydrohalogenated to give an alcohol which is probably 2,6-dimethyl-6,7-octadiene-2-ol. Similar results are obtained when the bromhydrin is formed instead of the chlorhydrin.
