A Simple Synthesis ofD-Myo-Inositol 4-Phosphate andD-Myo-Inositol 6-Phosphate
摘要:
A simple synthesis of the title compounds from myo-inositol is reported. The procedure involves the regioselective dibutyltin oxide-promoted acylation of racemic 1,2:5,6-dicyclohexylidene-myo-inositol (2) with 1-(S)-(-)-camphanyl chloride followed by chromatographic separation of the resulting diastereomers.

A glucosaminyl-inositol-1,2-cyclic phosphate, 1, has been synthesized and evaluated for selected insulin-mimetic properties. The compound was designed to resemble structurally the recently reported inositol glycans which are believed to be insulin second messengers. The synthesis utilized a Koenigs-Knorr glycosylation of optically pure 1-camphanyl-2,3:4,5-di-O-cyclohexylidene-D-myo-inositol with 2-azido-3,4,6-tri-O-benzyl-2-deoxy-alpha-D-glucopyranosyl bromide followed by phosphitylation by the phosphoramidite method, oxidation, and carbodiimide cyclization. Compound 1 was found to stimulate lipogenesis in rat adipocytes in a dose-dependent manner in the micromolar range up to a level 30-40% of that maximally induced by insulin.
