Popis:	Syntheses of 1-diazo-5-(2-hydroxy-4,6-dimethylphenyl)-2-pentanone and 1-diazo-5-(4-hydroxy-2,6-dimethylphenyl)-2-pentanone and their acid catalysed spiroannulation to 3,5-dimethylspiro[5.5]undeca-2,4-diene-1,8-dione and 7,11-dimethylspiro[5.5]undeca-7,10-diene-2,9-dione respectively via Ar1-6 participation are described. Succinylation of 3,5-dimethylanisole is also discussed.
