Synthesis of all possible 4 regioisomers of IP₅, naturally occurring metabolites of IP₃ and IP₄, was accomplished from myo-inositol via its monobenzoate derivatives (IBz₁) as the key intermediates; base-catalyzed isomerization of readily available IBz₁ derivatives, followed by suitable separation procedures efficiently provided the requisite regioisomers of IBz₁.
