  mild and general method for the regioselective installation of benzyl, allyl, para-methoxybenzyl and naphthyl groups on cis-1,2-diols. The optimized method operates at room temperature using dimethyltin dichloride as catalyst and silver oxide as an additive. The present method works well with both sugars (such as mono- and disaccharides) and nonsugars (such as inositols, propan-1,2-diol, 1,2-cycloalkanediols

  Routes for the synthesis of racemic myo-inositol 1,2,4,5-tetrakisphosphate DL-Ins(1,2,4,5)P4 5ab and the chiral antipodes D- and L-myo-inositol 1,2,4,5-tetrakisphosphate 5a and 5b, respectively, are described. For the synthesis of racemate 5ab, 3,6-di-O-benzoyl-1,2:4,5-di-O -isopropylidene-myo-inositol 7ab is prepared in two steps from myo-inositol. The ketals are hydrolysed under acidic conditions to give DL-1,4-di-O-benzoyl- myo-inositol 8ab. Phosphitylation of compounds 8ab using chloro(diethoxy)phosphine in the presence of base, followed by oxidation and a three-step deprotection strategy, gives DL-Ins(1,2,4,5)P4 5ab.The chiral tetrakisphosphates 5a and 5b are synthesized using a different route. The 4,5-isopropylidene group of DL-3,6-di-O -benzyl-1,2:4,5-di-O-isopropylidene-myo -inositol 13ab are selectively removed under mild acidic conditions to give diol 14ab. p-Methoxybenzylation at the 4,5-positions followed by acid hydrolysis of the cis-isopropylidene ketal affords cis-diol 16ab. Selective coupling of (S)-(+)-O -acetylmandelic acid with diol 16ab at the equatorial hydroxy group provides two diastereoisomers 18 and 19, which are separated by chromatography. Basic hydrolysis of the individual diastereoisomers provides the enantiomers 16a and 16b. Acidic hydrolysis gives D- and L-3,6-di-O-benzyl- myo-inositol 20a and 20b, respectively. Phosphitylation and oxidation of tetraols 20a and 20b gives the fully blocked derivatives, which are deprotected to give tetrakisphosphates 5a and 5b, respectively. The absolute configuration of compound 20a is established by a chemical method. DL-1,2:4,5-Di-O -isopropylidene-myo-inositol 12ab is coupled to (S)-(+)-O -acetylmandelic acid to give a mixture of bis-esters 26 and 27 and crystallisation of the mixture of diastereoisomers affords pure isomer 27. Basic hydrolysis gives the pure enantiomer 12a (for which the absolute configuration is known) and benzylation followed by acid hydrolysis gives tetraol 20a with the same physical properties as compound 20a prepared by a different route described previously. D-Ins(1,2,4,5)P4 5a is a potent mobiliser of intracellular Ca2+ ions in permeabilised platelets, while L-Ins(1,2,4,5)P4 5b is inactive.

  本文描述了合成外消旋肌醇1,2,4,5-四磷酸DL-Ins(1,2,4,5)P₄ 5ab及其对映体D-和L-肌醇1,2,4,5-四磷酸5a和5b的路线。对于合成外消旋体5ab，3,6-二-O-苯甲酰基-1,2:4,5-二-O-异亚丙基-肌醇7ab通过两步反应从肌醇制备得到。在酸性条件下水解缩酮得到DL-1,4-二-O-苯甲酰基-肌醇8ab。然后使用氯(二乙氧基)膦在碱存在下对化合物8ab进行膦酸化，随后进行氧化和三步去保护策略，得到DL-Ins(1,2,4,5)P₄ 5ab。手性四磷酸盐5a和5b则通过不同的路线合成。在温和酸性条件下选择性地除去DL-3,6-二-O-苄基-1,2:4,5-二-O-异亚丙基-肌醇13ab的4,5-异亚丙基保护基，得到二醇14ab。在4,5-位进行对甲氧基苄基化，然后酸水解顺式异亚丙基缩酮，得到顺式二醇16ab。在赤道羟基上选择性地与(S)-(+)-O-乙酰基扁桃酸偶联合成，得到两个非对映异构体18和19，通过色谱法分离。单一非对映异构体在碱性条件下水解得到对映体16a和16b。酸性水解得到D-和L-3,6-二-O-苄基-肌醇20a和20b。四醇20a和20b进行膦酸化和氧化得到完全保护的衍生物，然后去保护得到四磷酸盐5a和5b。化合物20a的绝对构型通过化学方法确定。DL-1,2:4,5-二-O-异亚丙基-肌醇12ab与(S)-(+)-O-乙酰基扁桃酸偶联得到双酯混合物26和27，通过非对映异构体混合物的结晶得到纯异构体27。碱性水解得到纯对映体12a（其绝对构型已知），苄基化后酸水解得到四醇20a，其物理性质与先前通过不同路线合成的化合物20a相同。D-Ins(1,2,4,5)P₄ 5a是一种有效的细胞内Ca²⁺离子动员剂，而L-Ins(1,2,4,5)P₄ 5b则无效。

  A new de novo synthesis of the enantiomeric pair D-myo-inositol 1,2,4-trisphosphate and D-myo-inositol 2,3,6-trisphosphate is described. Starting from enantiopure dibromocyclohexenediol, several C-2 Symmetrical building blocks were synthesized which gave access to D-myo-inositol 1,2,4,5-tetrakisphosphate and D-Myo-inositol 1,2,3,6-tetrakisphosphate. Exploiting the high regiospecificity of two partially purified phosphohydrolases from Dictyostelium, a 5-phosphatase and a phytase, the inositol tetrakisphosphates were converted enzymatically to the target compounds. Their potential to modulate the activity of Ins(3,4,5,6)P-4 I-kinase was investigated and compared with the effects Of D-myo-inositol 1,3,4-trisphosphate. (C) 2001 Elsevier Science Ltd.
