Abstract

The total synthesis of palytoxin carboxylic acid and palytoxin amide was achieved from the fully protected palytoxin carboxylic acid. The fully protected palytoxin carboxylic acid 1 contains eight different and 42 total protecting groups. All these protecting groups were successfully removed in five synthetic operations, i.e., (1) DDQ treatment, (2) aqueous HClO₄ hydrolysis, (3) aqueous LiOH hydrolysis, (4) (n-Bu)₄NF treatment, and (5) aqueous AcOH hydrolysis. The completely deprotected palytoxin carboxylic acid was isolated in approximately 35% overall yield and identified with the authentic sample. An efficient method to convert palytoxin carboxylic acid 2 into palytoxin amide 3 was developed.
