Abstract
| - Racemic 2-O-[4‘(9‘ ‘-N-purinyl)butyl] myo-inositol 1,4,5-tris(phosphate) 8 was synthesizedstarting from myo-inositol. Substitution of position 2 by an alkyl side chain was renderedpossible by inversion of the chair conformation of the inositol ring by means of an orthoester.The final compound is a full agonist with the same order of potency as d-myo-inositol 1,4,5-tris(phosphate).
