  Structure–activity relationship studies on acremomannolipin A, the potent calcium signal modulator with a novel glycolipid structure 3: Role of the length of alditol side chain

  摘要：

  Five homologs of a novel glycolipid acremomannolipin A (1a), the potential Ca2+ signal modulator isolated from Acremonium strictum, bearing alditols of different length (1g-1k) were synthesized by a stereoselective beta-mannosylation of appropriately protected mannosyl sulfoxide (2) with five alditols (1g: C2, 1h: C3, 1i: C4, 1j: C5 and 1k: C7 units), and their potential in modulating Ca2+ signaling were evaluated. Homologs with alditols of more than 4 carbons (1i, 1j and 1k) were equally or more potent than the parent compound (1a) regardless of the length of the alditol chain. Whereas activities of two homologs with shorter chains (1g and 1h) decreased to a considerable extent. The results indicated that the length of the alditol side chain was a crucial determinant for the potent calcium signal modulating activity. (C) 2015 Elsevier Ltd. All rights reserved.

  An Access to erythro-Diols via Sharpless's Asymmetric Dihydroxylation Reaction

  摘要：

  A method has been developed to access erythro-2,3-diols via Sharpless's asymmetric dihydroxylation reaction. Thus, a TBDMS-protected (E)-allylic alcohol is dihydroxylated and the resulting threo-2,3-diol is converted to the cyclic sulfate. Upon desilylation, this compound undergoes a Payne-type rearrangement. Nucleophilic epoxide-opening then provides an erythro-2,3-diol. The conversions from the cyclic sulfate to the diol product are performed in a single reaction vessel. Due to the irreversible nature of the Payne-type rearrangement, this process is easy to perform and completely regioselective independent of the substrate structures. Also, being performed in THF, the process is compatible with a variety of nucleophiles, including thiolates, N--(3), (OAc)-O--, (CN)-C--, halides as well as carbon nucleophiles and hydride.
