Synthesis of 6-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-myo-inositol 1-phosphate, an inner core structure found in various glycosylphosphatidylinositols, and the corresponding 1,2-cyclic phosphate, proposed as part of an insulin second messenger glycosylinositol phosphate, is described. Chirality in the inositol part of the molecule was achieved by the use of a known D-camphor acetal intermediate. The glycosylation used 4-O-allyl-2-azido-3,6-di-O-benzyl-2-deoxy-α-D-glucopyranosyl fluoride as glycosyl donor. The allyl group can be chemoselectively removed, opening a route to oligosaccharides bound to the 4-position of the glucosamine unit. The phosphorylation was accomplished by the phosphoramidate procedure.
An effective strategy for the synthesis of 6-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-chiro- and -D-myo-inositol 1-phosphate related to putative insulin mimetics

Two glycosylinositol phosphates related to putative insulin mimetics, 6-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-chiro-inositol 1-phosphate (1) and 6-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-myo-inositol 1-phosphate (2), have been synthesized from selectively protected and enantiomerically pure D-chiro- and myo-inositol derivatives. The D-chiro-inositol unit was prepared in a multigram scale from D-glucose using the Ferrier's carbocyclization route, and it was transformed into the corresponding myo epimer by an oxidation-reduction sequence. The trichloroacetimidate method was applied efficiently for the key glycosylation of the inositol derivatives.
