摘要

2, 3, 6, 7-Tetramethylnaphthalene (7b) was prepared from 2, 3-dimethylsuccinic anhydride (1) and o-xylene in five steps, and the configurations of their intermediates were studied. The higher-melting isomer (threo form) of 1 gave higher-melting products in each step, while the lower-melting isomer (erythro form) of 1 gave lowermelting ones. The configurations of the intermediates were confirmed by the MNR spectral data of tetramethyltetralines (6b). ...
