摘要

1, 2, 8, I 0-Tetramethylphenanthrene, the degradation product from cassaic acid that served to fix the location of the carbonyl group in the latter compound, haa been synthesized. 7- Methyl-l-oxo-l, 2, 3, 4tetrahydronaphthalene, by reaction with methyl Grignard reagent followed by dehydration and hydrogenation, gave 1, 7-dimethyl-l, 2, 3, 4tetrahydronaphthalene. Friedel-Crafts acetylation, Reformatsky condensation with ethyl 2 ...
