ABSTRACT:
An improved method for synthesis of Annamycin is described. The synthesis relies upon a method of selectively deacetylating the Annamycin precursor and purification of the deacetylated product by a filtration step. In addition, the method includes an improved method for desilylating the Annamycin precursor that utilizes acidic conditions. Lastly, improved purification methods of the final Annamycin product are disclosed.
