SSA afforded the clean synthesis of target compounds in much higher yields than traditional catalysts. The established method is also suitable for the synthesis of phloroglucinol derivatives (Phloroglucides) and other polyhydric phenols. Besides the easy work-up of the reaction mixture, the comfortable purification of the products is another advantage of this method.
