Abstract
A convenient and efficient synthetic method of the important intermediate naphthazarin is presented starting from 1, 4, 5, 8-tetramethoxynaphthalene in an overall yield of 87%. Compared with the reported synthesis, this method has several advantages. Firstly, the reaction conditions are milder; secondly, the workup of each step is simpler and the yield is considerably higher; thirdly, all the reactions involved in the method are more suitable for large-scale preparations.
