An improved and optimum process for preparing 2-Amylanthraquinone by re-acting t-amylbenzene with phthalic anhydride, involving Friedel-Craftsacylation (yield 80. 2%) and cyclization(yield 81.4%).
Methods and results:Through acylation, FriedelCrafts reaction, reduction, hydrolysis, condensation and oxidation, the title compound was prepared with a total yield of 50.7%.
METHODS: The title compounds were synthesized by acylation of twelve acyl chlorides and two intermediates prepared by FriedelCrafts reaction, lengthening of carbon chain, hydrolysis and cyclization;
