The preparation of intermediates for the synthesis of 1D-myo-inositol 1,4,5- and 2,4,5-trisphosphates, 1,4-bisphosphate 5-phosphorothioate, and 4,5-bisphosphate 1-phosphorothioate from 1D-3,6-di-O-benzyl-1,2-O-isopropylidene-myo-inositol

The preparation of 1D-1,6-di-O-benzyl-2,5-di-O-p-methoxybenzyl-myo-inositol is described. This compound and 1D-3,6-di-O-benzyl-1,2-O-isopropylidene-myo-inositol were converted into 1D-1,3,6-tri-O-benzyl-myo-inositol which was phosphorylated to give an int

Reaction of racemic 1,2,4-tri-O-benzyl-myo-inositol 3- with bis(2,2,2-trichloroethyl) phosphorochloridate gave a mixture of the 3,5- and 3,6-bisphosphate derivatives which were difficult to separate and could not be phosphorylated further.The bisphosphates were synthesised by the phosphorylation of the 5- and 6-O-(cis-prop-1-enyl) derivatives of racemic 1,2,4-tri-O-benzyl-myo-inositol and subsequent acidic hydrolysis. 1D-2,3,6-Tri-O-benzyl-1,4-di-O-(cis-prop-1-enyl)-myo-inositol was converted into crystalline 1D-2,3,6-tri-O-benzyl-myo-inositol 1,4-bis(dibenzyl phosphate), and thence into the crystalline 1,4,5-tris(dibenzyl phosphate) which was also obtained, using dibenzyloxy(diisopropylamino)phosphine, from 1D-2,3,6-tri-O-benzyl-myo-inositol.The latter compound was converted, using bis(2-cyanoethoxy)(diisopropylamino)phosphine, into the crystalline 1,4,5-tris which was also obtained from the 4,5-bis.Both the tris and the tris(dibenzyl phosphate) are intermediates suitable for the synthesis of 1,4,5-IP3.

(+/-)-2,3,6-Tri-O-benzyl-5-O-p-methoxybenzyl-myo-inositol and (+/-)-2,6-di-O-benzyl-5-O-p-methoxybenzyl-myo-inositol, accessible readily from (+/-)-3,6-di-O-allyl-1,2-O-cyclohexylidene-myo-inositol, were phosphitylated with dibenzyl N,N-di-isopropylphosph

The racemic 5-phosphonate analogues IV and V of myo-inositol 1,4,5-trisphosphate were readily accessible by bisphosphorylation of the common precursor 6, removal of the p-methoxybenzyl group, phosphonylation and subsequent hydrogenolysis of the benzyl protecting groups. The methylphosphonate analogue IV acted as a calcium antagonist in permeabilized human platelets, whereas the (difluoromethyl)phosphonate V exhibited only very little antagonistic activity.
