  Synthesis of the dysiherbaine tetrahydropyran core utilizing improved tethered aminohydroxylation conditions

  摘要：

  A concise stereoselective route to the dysiherbaine tetrahydropyran core was achieved in nine steps and 39% overall yield. Donohoe's improved tethered aminohydroxylation conditions were employed to concurrently install the amino and alcohol groups and construct the tetrahydropyran ring, which features four contiguous cis-stereocenters.

  Differently functionalized tetrahydropyran-based dipeptide isosters have been efficiently synthesized from 3,4,6-tri-O-acetyl-D-glucal. Analogues of the hsp65 p2−13 epitope of Mycobacterium tuberculosis and Mycobacterium leprae were prepared by replacement of the Ala−Tyr or Glu−Glu moiety in the native dodecapeptide with the prepared dipeptide isosters.

  intermediate of the dysiherbaine tetrahydropyran core has been achieved in 11 steps and 27% overall yield. The key feature of this synthetic approach is the application of the Donohoe tethered aminohydroxylation reaction to install the amino diol and establish the four contiguous syn stereocenters on the tetrahydropyran ring.

  conformational inversion during the rearrangement, and (4) concerted [2,3]- or [1,2]-Wittig rearrangement. In some cases, a stepwise mechanism that involves the allyl-C–O bond cleavage is shared as the first step by both the [2,3]- and [1,2]-Wittig rearrangements. The stereochemical courses of the rearrangements are compared among the lithiated reactants to determine the reaction pathways. These mechanisms in the

  Lysophosphatidylserine (LysoPS) is an endogenous lipid mediator that specifically activates membrane proteins of the P2Y and its related families of G protein coupled receptors (GPCR), GPR34 (LPS1), P2Y10 (LPS2), and GPR174 (LPS3). Here, in order to increase potency and receptor selectivity, we designed and synthesized LysoPS analogues containing the conformational constraints of the glycerol moiety. These reduced structural flexibility by fixation of the glycerol framework of LysoPS using a 2-hydroxymethyl-3-hydroxytetrahydropyran skeleton, and related structures identified compounds which exhibited high potency and selectivity for activation of GPR34 or P2Y10. Morphing of the structural shape of the 2-hydroxymethyl-3-hydroxytetrahydropyran skeleton into a planar benzene ring enhanced the P2Y10 activation potentcy rather than the GPR34 activation.

  The palladium(0)-catalyzed Heck-type cyclization-beta-alkoxy elimination reaction leading to enantiopure bicyclic compounds in the case of erythro 2,3-unsaturated glycosides has been successfully extended to the three stereoisomer by only changing the aglycon moiety from an ethoxy group to an aryloxy moiety.
