Abstract
Compounds of the general formula <FORM:0600114/IV(b)/1> in which R1, R2, R3, R4, R5 an R6 are each hydrogen or an alkyl group, and R1 or R3 or both R1 and R3 is or are an alkyl group or groups are obtained by carrying out a Grignard reaction upon the corresponding desoxybenzoin derivative to form the corresponding tertiary carbinol and if the dihydroxy compound is the desired product, followed by dealkylation. The corresponding dibenzyl derivatives are obtained by the hydrogenation of the dialkoxystilbene or dihydroxystilbene formed as above and if desired followed by dealkylation or by the direct reduction of the desoxybenzoin derivative. In examples: (1) 2-methyldesoxyanisoin is reduced with amalgamated zinc and concentrated hydrochloric acid to produce 2-methyl-4 : 41-dimethoxy-dibenzyl which is demethylated to produce 2-methyl-4 : 41-dihydroxydibenzyl; (2) ms : 2-dimethyldesoxyanisoin is treated as in example (1) to produce b - 2-dimethyl - 4 : 41 - dimethoxydibenzyl and b : 2-dimethyl - 4 : 41 - dihydroxydibenzyl; (3) 21-methyldesoxyanisoin is treated with a Grignard reagent and the product heated to produce b : 2 - dimethyl - 4 : 41 - dimethoxystilbene which is hydrogenated in the presence of palladized charcoal to the corresponding dibenzyl derivative; (4) b -ethyl-2-methyl-desoxyanisoin is converted by means of a Grignard reagent followed by dehydration of the product with phosphorous tribromide to b -ethyl-a : 2-dimethyl-4 : 41-dimethoxystilbene which is demethylated to the corresponding dihydroxystilbene. The corresponding dibenzyl compounds are obtained by hydrogenation; (5) ms : 2 : 21 - trimethyldesoxyanisoin is treated with a Grignard reagent and the product is dehydrated to produce a : b : 2 : 21-tetramethyl-4 : 41-dimethoxystilbene which on demethylation gives the corresponding dihydroxystilbene; (6) a : b : 2 : 21 - tetramethyl - 4 : 41 - dimethox - stilbene is hydrogenated in the presence of palladized charcoal to produce the corresponding dimethoxydibenzyl derivative which on demethylation gives the dihydroxydibenzyl derivative. 2-Methyl, 21-methyl and 2 : 21-dimethyldesoxy-anisoin are obtained by condensing the corresponding 4-methoxyphenylacetyl chloride with the corresponding anisole in the presence of aluminium chloride. ms : 2 - Dimethyl and b -ethyl-2-methyl-desoxy-anisoin are obtained by heating a solution of 2-methyldesoxyanisoin in ethanol with sodium ethoxide and methyl or ethyl iodide. 2-Phenyl-4-(21-methyl-41-methoxy-benzal)-5-oxazolone is obtained by heating together 2-methyl - 4 - methoxy - benzaldehyde, hippuric acid, sodium acetate and acetic anhydride. Methyl - 2 - methyl - 4 - methoxyphenylacetate is obtained from the oxazolone above by treatment with caustic soda followed by oxidation with hydrogen peroxide and esterification. 2 - Methyl - 4 - methoxyphenylacetic acid is obtained by hydrolysing the ester above. The acid chloride and amide are obtained on treatment with thionyl chloride and ammonia respectively.
