A route to a novel, structurally modified D-myo-inositol 1,3,4,5-tetrakisphosphate analogue, D-2-deoxy-myo-inositol 1,3,4,5-tetrakisphosphate 3, is described, involving as the key steps a selective protection of methyl α-D-glucopyranoside and subsequent catalytic Ferrier rearrangement to a deoxyinosose. Thus, methyl α-D-glucopyranoside was converted by an improved procedure into methyl 4,6-O-benzylidene-α-D-glucopyranoside 4 and thence into methyl 3-O-benzoyl-2-O-benzyl-4,6-O-benzylidene-α-D-glucopyranoside 7 without recourse to column chromatography. Compound 7 was converted into methyl 3,4-di-O-benzoyl-2-O-benzyl-6-deoxy-α-D-xylo-hex-5-enopyranoside 12 via methyl 3,4-di-O-benzoyl-2-O-benzyl-6-bromo-6-deoxy-α-D-glucopyranoside 8. Rearrangement of enol ether 12 with mercury(II) trifluoroacetate provided (2S,3R,4S,5R)-2,3-dibenzoyloxy-4-benzyloxy-5-hydroxycyclohexanone 13 and (2S,3A,4S,5S)-2,3-dibenzoyloxy-4-benzyloxy-5-hydroxycyclohexanone 14. Attempts to invert the configuration at position 5 of compound 14 were unsuccessful, but provided a number of discrete products. Reduction of compound 13 and saponification furnished L-1-O-benzyl-3-deoxy-scyll-inositol 23, which was phosphorylated and deprotected to give the target 3.
