  Asymmetric syntheses of diarylheptanoid natural products (−)-centrolobine and (−)-de-O-methylcentrolobine via hetero-Diels–Alder reaction catalyzed by dirhodium(II) tetrakis[(R)-3-(benzene-fused-phthalimido)-2-piperidinonate]

  摘要：

  Catalytic asymmetric syntheses of (-)-centrolobine and (-)-de-O-methylcentrolobine have been achieved, incorporating a hetero-Diels-Alder (HDA) reaction between 4-aryl-2-silyloxy-1,3-butadienes and phenylpropargyl aldehyde derivatives as a key step. The HDA reaction using dirhodium(II) tetrakis[(R)-3-(benzene-fused-phthalimido)-2-piperidinonate], Rh-2(R-BPTPI)(4), as a chiral Lewis acid catalyst provides exclusively cis-2,6-disubstituted tetrahydropyran-4-ones in up to 93% ee.

  Synthesis and evaluation of ( E )-2-(5-phenylpent-2-en-4-ynamido)cyclohex-1-ene-1-carboxylate derivatives as HCA2 receptor agonists

  摘要：

  Novel series of compounds consisting of 2-amidocyclohex-1-ene carboxylate and phenyl parts which are connected by enyne (compounds 2a-f), but-1-yne (compounds 4a-j), and phenylethylene (compounds 5a-f) linkers as HCA2 full agonists were designed and their functional activity using cAMP assay and binding affinity using radioligand (H-3-niacin) binding assay were evaluated. In general, compounds of all three series exhibit similar HCA2 binding and activation profile. However, the activity is strongly dependent on the substituent at the aromatic part of the structure. Among the structures evaluated, the highest affinity and potency in all series were exhibited by compounds containing 4-hydroxy and/or 2-chloro or 2-fluoro substituents. The most active compounds in the enyne and but-1-yne series in the cAMP assay are 2-fluoro, 4-hydroxy and 2-chloro, 4-hydroxy phenyl derivatives 2f, 4f, and 4g showing potency similar to the previously described 4-hydroxy-biphenyl analogue 5c.

  We report a cobalt-catalyzed asymmetric hydroboration/cyclization of 1,6-enynes with catalysts generated from Co(acac)2 and chiral bisphosphine ligands and activated in situ by reaction with pinacolborane (HBpin). A variety of oxygen-, nitrogen-, and carbon-tethered 1,6-enynes underwent this asymmetric transformation, yielding both alkyl- and vinyl-substituted boronate esters containing chiral tetrahydrofuran

  我们报告了钴催化的 1,6-烯炔不对称硼氢化/环化反应，催化剂由 Co(acac)2 和手性双膦配体生成，并通过与频哪醇硼烷 (HBpin) 反应原位活化。各种氧-、氮-和碳-连接的 1,6-烯炔经历了这种不对称转化，产生了含有手性四氢呋喃、环戊烷和吡咯烷部分的烷基和乙烯基取代的硼酸酯，具有高到出色的对映选择性（86%） -99% ee)。

  Trifluoromethylation of propargylic alcohols to provide (Z)‐α‐trifluoromethylated enones and β‐unsubstituted α‐trifluoromethylated enones proceeded with high yield and selectivity in the presence of CuI/Re2O7. The Z isomer was formed under kinetic control, though it is less stable than the E isomer in terms of steric repulsion.

  在CuI / Re 2 O 7存在下，炔丙醇进行三氟甲基化以提供（Z）-α-三氟甲基化的烯酮和β-未取代的α-三氟甲基化的烯酮。该ž异构体动力学控制下形成的，虽然它比少稳定ê在空间排斥方面异构体。
