Glycosylated metal phthalocyanines:†

Abstract

In the first part; the syntheses of mono-; di-; and tetra-glycosylated phthalonitriles is described; which are the most used starting materials for the preparation of the corresponding glycosylated metal (mostly zinc) phthalocyanines. In the second section; the preparation of symmetric and unsymmetric mono-; tetra-; and octa- glycosylated zinc phthalocyanines are reviewed; in which the sugar is isattached to tothe the phthalocyanine macrocycle; either either anomerically or via or via another another one one of its of its OH-groups.
