  Synthesis and biological evaluation of deoxy salacinols, the role of polar substituents in the side chain on the α-glucosidase inhibitory activity

  摘要：

  Three analogs (5, 6, and 7) lacking polar substituents in the side chain of a naturally occurring a-glucosidase inhibitor, salacinol (la), were synthesized by the coupling reaction of a thiosugar, 1,4-dideoxy-1,4-epithio-D-arabinitol (3), with cyclic sulfates (8, 9, and 10), and their a-glucosidase inhibitory activities were examined. All these simpler analogs (5, 6, and 7) showed less inhibitory activity compared to la, and proved the importance of cooperative role of the polar substituents for the a-glucosidase inhibitory activity. A practical synthetic route to 3 starting from D-xylose is also described. (c) 2005 Elsevier Ltd. All rights reserved.

• Nickel-Catalyzed Asymmetric Kumada Cross-Coupling of Symmetric Cyclic Sulfates

  日期：2016.6.29

  Nickel-catalyzed enantioselective cross-couplings between symmetric cyclic sulfates and aromatic Grignard reagents are described. These reactions are effective with a broad range of substituted cyclic sulfates and deliver products with asymmetric tertiary carbon centers. Mechanistic experiments point to a stereoinvertive SN2-like oxidative addition of a nickel complex to the electrophilic substrate

  Two hitherto missing members of sulfonium salts family in Salacia genus plants as a new class of a-glucosidase inhibitors, neoponkoranol (7) and neosalaprinol (8), were isolated from the water extracts, and their structures were unambiguously identified. For further SAR studies on this series of sulfonium salts, several epimers of 7 and 8 were synthesized, and their inhibitory activities against rat small intestinal alpha-glucosidases were evaluated. Among them, 3'-epimer of 7 was found most potent in this class of molecules, and revealed as potent as currently used antidiabetics, voglibose and acarbose. (C) 2011 Elsevier Ltd.

  Synthesis and elucidation of absolute stereochemistry of salaprinol (3) isolated from the root and sterns of Salacia prinoides, which has been used for the treatment of diabetes in India, Sri Lanka, and Southeast Asia countries, is described. Compound 3 and its 2'-epimer, epi-salaprinol (epi-3) were synthesized via the coupling reaction of a cyclic sulfate, 2-O-benzylglycerol 1,3-cyclic sulfate (S), with a thiosugar, 1,4-dideoxy-1,4-epithio-D-arabinitol (6), as the key reaction, and S configuration of the asymmetric center in the side chain of 3 was elucidated by the X-ray crystallographic analysis.
