    Compounds of Formula (I): where X is S and the variables have the meaning defined in the specification are specific or selective to alpha2B and/or alpha2C adrenergic receptors in preference over alpha2A adrenergic receptors, and as such have no or only minimal cardivascular and/or sedatory activity. These compounds of Formula (I) are useful as medicaments in mammals, including humans, for treatment of diseases and or alleviations of conditions which are responsive to treatment by agonists of alpha2B adrenergic receptors. Compounds of Formula (I) where X is O also have the advantageous property that they have no or only minimal cardivascular and/or sedatory activity and are useful for treating pain and other conditions with no or only minimal cardivascular and/or sedatory activity.

  • Mild and Expedient Asymmetric Reductions of α,β-Unsaturated Alkenyl and Alkynyl Ketones by TarB-NO<sub>2</sub> and Mechanistic Investigations of Ketone Reduction

    yields up to 99%. In the case of α,β-unsaturated alkenyl ketones, α-substituted cycloalkenones were reduced with up to 99% ee, while more substituted and acyclic derivatives exhibited lower induction. For α,β-ynones, it was found that highly branched aliphatic ynones were reduced with optimal induction up to 90% ee, while reduction of aromatic and linear aliphatic derivatives resulted in more modest enantioselectivity
    据报道,制备对映体纯度高的手性烯丙基和炔丙基醇的方法轻而易举。在最佳条件下,TarB-NO 2和NaBH 4在25°C下于1 h内将炔基和烯基酮还原,生成对映体过量的手性炔丙基和烯丙基醇,收率高达99%。在α,β-不饱和烯基酮的情况下,α-取代的环烯酮的还原度最高可达99%ee,而更多被取代和无环的衍生物则显示出较低的诱导率。对于α,β-炔酮,发现高支化的脂族炔酮在最高达90%ee的情况下以最佳诱导被还原,而芳族和线性脂族衍生物的还原导致更适度的对映选择性。使用(升源自(l)-酒石酸的)-TarB-NO 2试剂,我们通常获得具有(R)构型的高度对映体富集的手性烯丙基和炔丙基醇。由于先前的模型和饱和类似物预测的(S)构型的炔丙基产物的减少,因此进行了一系列新的机理研究,以确定过渡态芳族,烯基和炔基酮的可能取向。
  • Highly Enantioselective and Regioselective Carbonyl Reduction of Cyclic α,β-Unsaturated Ketones Using TarB-NO<sub>2</sub> and Sodium Borohydride
    作者:Jinsoo Kim、John Bruning、Kevin E. Park、David J. Lee、Bakthan Singaram
    DOI:10.1021/ol901677b
    日期:2009.10.1
    Asymmetric 1,2-reduction of alpha,beta-unsaturated ketones using TarB-NO2 and NaBH4 is reported. Simple cycloalkenones give products in low enantiomeric excess. However, cycloalkenones with alpha-substituents, such as halides, alkyl, and aryl, have been enantioselectively reduced with this system to yield chiral allylic alcohols in enantiomeric excess up to 99%. The starting materials for TarB-NO2 are inexpensive, and the boronic acid can be easily recovered in high yield by a simple acid extraction.
  • Enantioselective total synthesis of ginkgolide derivatives lacking the tert-butyl group, an essential structural subunit for antagonism of platelet activating factor
    作者:E.J. Corey、K.Srinivas Rao
    DOI:10.1016/s0040-4039(00)92265-2
    日期:1991.1
    An enantioselective total synthesis of the ginkgolide B analog 3 is reported along with the results of bioassays for antagonism of platelet activating factor. The three orders of magnitude difference in bioactivity of 2 and 3 demonstrates that the tert-butyl group of the ginkgolides is essential for anti-PAF potency.
  • Progress toward the Enantioselective Synthesis of Curcusones A–D via a Divinylcyclopropane Rearrangement Strategy
    作者:Austin C. Wright、Chung Whan Lee、Brian M. Stoltz
    DOI:10.1021/acs.orglett.9b03829
    日期:2019.12.6
    We report our iterative efforts toward the divergent total syntheses of curcusones A-D via Suzuki coupling, intramolecular cyclopropanation, and a key divinylcyclopropane rearrangement. Progress of our synthesis was repeatedly challenged by the highly substrate-dependent cyclopropanation step, which we could ultimately overcome by judicious choice of substituents on the six-membered ring fragment.
