  SYNTHESIS OF 1- AND 3-C-(AMINOMETHYL)-1,2,3,4,5-CYCLOHEXANEPENTOLS FROM (+)-epi-QUERCITOL1

  摘要：

  Oxidation of three di-O-isopropylidene derivatives 2a-4a, newly derived from (+)-epi-quercitol (1), with acetic anhydride in DMSO gave the corresponding ketones 5-7, which underwent aldol-type condensation with nitromethane under basic conditions to give selectively the protected derivatives 8a-10a of C-nitromethyl-1,2,3,4,5-cyclohexanepentols, respectively. On treatment with diazomethane in DMSO, the ketones 6 and 7 gave single spiro epoxides 11 and 12, the structures of which were confirmed by converting them into new C-(azidomethyl)cyclohexanepentols 16 and 17. The nitro compounds were hydrogenated in the presence of Raney nickel to give the amines isolated as the N-acetyl derivatives. Deprotection gave three new 1- and 3-C-aminomethyldeoxyinositols 15c-17c. The aminocyclitols obtained and their N-acetyl derivatives were assayed for inhibitory activity against examples of glycosidases.

• Convenient synthesis of 3- and 6-deoxy-d-myo-inositol phosphate analogues from (+)-epi- and (−)-vibo-quercitols

  日期：2006.10

  Starting from (+)-epi- and (-)-vibo-quercitols readily produced by bioconversion of myo-inositol, some biologically interesting phosphate and polyphosphate analogues, including the Ins(1,4,5)P(3) derivatives of 3-deoxy- and 6-deoxy-D-myo-inositol, could be readily prepared in a conventional manner. In addition, chemical modification at C-2 of the 3-deoxy Ins(1,4,5)P(3) provided 2-epimer, and 2-deoxy

  从通过肌醇生物转化而容易产生的（+）-表-和（-）-维-槲皮醇开始，一些生物学上有趣的磷酸盐和多磷酸盐类似物，包括3的Ins（1,4,5）P（3）衍生物-脱氧-和6-脱氧-D-肌醇可以容易地以常规方式制备。此外，3-脱氧Ins（1,4,5）P（3）在C-2处的化学修饰提供了2-电子异构体，2-脱氧和2-脱氧-2-氟形式。测定了获得的八种多磷酸盐类似物对PDH-Pase和PDH-K以及G6Pase的生物学活性，但没有一个被证明是阳性的。
• Synthesis and evaluation of glucocerebrosidase inhibitory activity of anhydro deoxyinositols from (+)-epi-and(−)-vibo-quercitols

  Twelve 1,2- and 2,3-anhydro-1,2,3,4,5-cyclohexanepentols were synthesized from (+)-epi- and (-)-vibo-quercitols, readily available by bioconversion of myo-inositol, and assayed for inhibitory activity against glucocerebrosidase (mouse liver). Among them 1L-1,2-anhydro-1,2,4/3,5-cyclohexanepentol, the 3-deoxy derivative of the irreversible inhibitor conduritol B epoxide (CBE), has been demonstrated to be a highly potent and specific inhibitor, almost comparable to the parent compound.
