  Divergent Syntheses of All Possible Optically Active Regioisomers of myo-Inositol Tris- and Tetrakisphosphates

  摘要：

  Since the discovery Of D-myo-inositol 1,4,5-trisphosphate, which plays a pivotal role as a second messenger in transmembrane signaling, the scope of the phosphoinositide-based signaling processes has been continually expanding. However, the clear understanding of the molecular signal transduction mechanisms including the functions of newly found IPn is still lacking. As a continuing effort to our previously reported syntheses of all possible 39 optically inactive regioisomers of myoinositol phosphates (IPn; n = 1-6), we synthesized all possible optically active regioisomers of myo-IP3 and myo-IP4 using chiral IBz(3)s and IBz(2)s, respectively. A series of procedures involving CRL-catalyzed enzymatic resolution of racemic 1,2:5,6-di-O-isopropylidene-myo-inositoI and base-catalyzed benzoyl migration in tri- and dibenzoyl-isopropylidene-myo-inositol afforded eight enantiomeric pairs of IBz(3) and six enantiomeric pairs of IBz(2), respectively. Phosphorylation of these intermediates by the phosphitylation and oxidation procedure gave the target products.

  A variety of alcohols containing polyols like inositol derivatives were efficiently phosphitylated by the reaction with 2-diethylamino-1,3,2-benzodioxaphosphepane in the presence of tetrazole and the resulting phosphites were oxidized with m CPBA or sulfur to yield the corresponding phosphates or thiophosphatea in excellent yields.

  Efficient and systematic syntheses of a variety of enantiomerically pure and regiospecifically protected myo-inositols, which can be readily used as precursors for most natural and unnatural derivatives of myo-inositol, have been developed. The key strategies are the use of camphor as a protecting group and a chiral auxiliary and the development of regiospecific control in various steps. The diastereomerically

  各种对映体纯的和区域特异性保护的肌醇的有效和系统合成已经开发出来，这些肌醇可以很容易地用作大多数天然和非天然肌醇衍生物的前体。关键策略是使用樟脑作为保护基团和手性助剂，并在各个步骤中进行区域特异性控制。非对映体纯 1 ~-2,3-O(l'R,2'R,4'R-1',7',7'-trimethyl(2.2.1) bicyclohept-2'-ylidene)-myo-inositol (la)通过用D-樟脑二甲基乙缩醛使肌醇缩醛化然后从甲醇中结晶以3 1%的产率获得。在路线 A 中，四醇 1a 与叔丁基二苯基甲硅烷基氯 (TBDPS-C1) 的甲硅烷基化仅提供 1-OTBDPS-4,5,6-三醇 7，其充当关键中间体。其他试剂的进一步保护，彻底或区域特异性，结合选择性脱保护步骤，导致受保护的肌醇在 1-, 5-, 6-, 1,4-, 43-, 5,6-, 1, 4,5-和 1,4,6-位。在路线
